Trivia: Ever since his film debut in director Michael Mann's 1981 crime drama Thief, actor William L. Petersen (born February 21st, 1953) has carved a successful niche for himself in the realm of crime-oriented television and film. Audiences were quick to warm to the actor thanks to his everyman appearance and ability to elicit sympathy by portraying authority figures whose rank rarely surpassed their humanity, and in the following decades, Petersen would hone this persona to a fine point in such efforts as Mann's 1986 thriller Manhunter and, much later, the popular CBS crime series CSI: Crime Scene Investigation. It was while studying on a football scholarship at Idaho State University that the Evanston, IL, native first discovered his love for the stage, and though the popular jock initially signed up for drama classes as a means of boosting his grade point average, his love for the stage soon surpassed his grip on the gridiron. A post-graduate move to Spain found Petersen studying Shakespearean acting, with a subsequent return to the States leading the burgeoning actor to Chicago. In addition to an association with the famed Steppenwolf Theater, Petersen and several of his peers co-founded Chicago's Remains Theater Ensemble in 1980. The next year, a small supporting role in Mann's Thief marked Petersen's first foray into the celluloid universe, and it was also around this time that Petersen made his Broadway debut with a starring role in The Night of the Iguana. The actor remained a fixture on CSI until 2008, and went on to co-star in the films Detatchment (2011) and Seeking a Friend for the End of the World (2010).As the 1980s progressed, Petersen became an increasingly recognizable figure in the world of film, in particular thanks to solid performances in such efforts as To Live and Die in L.A., Manhunter, and Amazing Grace and Chuck, with his stature on the screen virtually cemented by the time he kicked off the 1990s with a turn as Pat Garrett in Young Guns II. Though roles in such films as Return to Lonesome Dove, Fear, and The Beast did indeed increase Petersen's recognition factor among the moviegoing and television-viewing masses, he more often than not seemed to be lost without Mann's direction and criminals to chase. Of course, all of this would be solved when the veteran actor stepped into the role of crime scene investigator for the 2000 television series CSI, and though feature work had certainly taken precedence over television thus far in his career, the transition seemed to benefit Petersen when the Emmy-nominated series soon shot to the top of the ratings.

Trivia: Best known for her television work, Marg Helgenberger started acting in college theatrical productions while studying speech at Northwestern University. A native of Omaha, NE, where she was born on November 16, 1958, Helgenberger moved to New York after graduating from college and landed a role as a tough young policewoman on the soap opera Ryan's Hope. During her four-year tenure on the show, she also maintained her ties with the theater through her involvement with TADA, the Children's Theater Company.Following a move to Southern California, Helgenberger began guest starring on such television series as Matlock, thirtysomething, and HBO's Tales From the Crypt. She co-starred on the short-lived series Shell Game (1987) before getting her big break with the role of K.C., a tough prostitute, on the distinguished drama China Beach in 1988. Helgenberger's role won her two Emmy nominations and one win in 1990. Following the series' demise in 1991, Helgenberger returned to television guest-star status on ER, where she had a four-episode-long recurring role, and in the miniseries The Tommyknockers.A presence on the big screen since 1989, when she made her feature-film debut in Steven Spielberg's romantic fantasy Always, Helgenberger has played a wide variety of roles in films ranging from Species (1995) to the moody The Last Time I Committed Suicide (1997) to Steven Soderbergh's widely acclaimed Erin Brockovich (2000). Helgenberger would continue to appear in films like In Good Company and Mr. Brooks, and found particular success with the starring role of Catherine Willows on the long running proceedural CSI: Crime Scene Investigation.

Trivia: Best known for his role as Warrick Brown, the detective with a marked predilection for risk (and an ongoing gambling addiction), on CBS's blockbuster series CSI: Crime Scene Investigation, the easygoing, congenial, and memorably handsome African-American actor Gary Dourdan has built his life and his public image around uniqueness and originality. Six foot two inches tall, green-eyed, sporting bushy yet sculpted dreadlocks, and straddling the worlds of drama and avant-garde music, Dourdan commented to Ebony magazine, "I've always tried to be unconventional as much as I possibly could...one thing I'm trying to do with my career and with my craft is to blur the lines between what people think African-Americans should play and what I'm doing. I'm not much into fads and fashions and trying to follow things."Born December 11, 1966, in Philadelphia, PA, as the son of Robert and Sandy Durdin (his actual surname), the adolescent Dourdan attended "Freedom Theater," an inner-city program for aspiring actors, during adolescence. Success in this venue prompted him to travel to Manhattan on a weekly basis for musical training and dramatic auditions. Dourdan landed his "big break" as an actor in the early '90s, seemingly without even trying. While dating fashion model Roshumba Williams around 1991 and vacationing with her in France, Dourdan was spotted by powerhouse Debbie Allen, then the producer and director of A Different World; impressed by his looks and manner, she invited him to audition for the series. He played Shazza Zulu, the resident "con man" of Hillman College -- a role he sustained through the end of 1992 (for less than one season), before moving on to new endeavors. Dourdan debuted onscreen inauspiciously, with a bit part as the Second Cartel Man in Weekend at Bernie's II. Additional roles included that of a copy guy in Ron Howard's The Paper (1994), Christie in Alien Resurrection, and Yates in the Andy Wilson-directed medical thriller Playing God (1997). In 2000, Dourdan landed his biggest break with the CSI role, for executive producer Jerry Bruckheimer -- and (when the program instantly shot up to number one) continued the part as the series progressed. The same year that he signed with Bruckheimer and company, Dourdan played Malcolm X in the telemovie Muhammad Ali: King of the World. As mentioned, Dourdan is also a prolific alternative musician (with solo albums to his credit) and a record producer. He married African-American model Williams in 1992; the couple divorced two years later. He has two children, a son, Lyric, and a daughter, Nyla (the daughter of Jennifer Sutton, whom Dourdan dated from 1995 to 2000). He voiced the character of Detective Crispus Allen in 2008's Batman: Gotham Knight, and took on a supporting role as a chef in Jumping the Broom (2011).

Trivia: Whether scanning a homicide scene for evidence or blasting up a motorcycle ramp at 120 miles per hour as one of the world's greatest daredevils, it seems there's little that square-jawed CSI star George Eads can't accomplish on the small screen. However, the future wasn't always so sunny for the decidedly down-to-earth star; Eads has most certainly earned his rank among television's best, thanks to a solid work ethic and the kind of steadfast determination that's been known to move mountains. Born in Fort Worth, TX, and raised in nearby Belton, it didn't take the Texas Tech graduate long to realize his calling -- and despite the fact that chiseled Texans with big-time aspirations are a dime a dozen in Hollywood, Eads was determined to stand apart from the crowd. Of course, nothing comes easy in Hollywood, and after making the rounds to various auditions during the daytime, the eager up-and-comer would earn his keep as a weight adjuster at the local Gold's Gym in the off hours. Persistence eventually paid off in the form of a supporting role on the little-seen nighttime soap opera Savannah, and though the show barely lasted one season, it did provide an ideal training ground for the relatively inexperienced Eads. In the years that followed, Eads continued to hone his craft with a recurring role on the hit series ER as well as numerous supporting performances in such blink-and-you-miss-them made-for-television pictures as The Ultimate Lie and Crowned and Dangerous. Eads' persistence eventually paid off, and he was hired for the key role of forensic analyst Nick Stokes in the breakout television hit CSI. Cast as a former college baseball star with a hero complex, Eads charmed audiences by creating a character that was as believable as he was personable. The show proved an enormous success, but the young star nearly lost the role forever by making the simple mistake of oversleeping on the day of his salary negotiations (CBS at first thought Eads was attempting to strong-arm them for more money, but the situation soon blew over when Eads apologized for his actions). Now seated comfortably at the top of the television food chain, Eads continued to make a name for himself with roles in numerous made-for-television features including Just a Walk in the Park and Monte Walsh, though it was a role as his childhood hero Evel Knievel in a small-screen biography that truly brought Eads' career full circle. When he's not investigating some of the most grisly crimes ever witnessed on the small screen in CSI, Eads fulfills his duties as part owner of Hollywood's popular Cinespace restaurant -- a perfect place to take in dinner and a movie.

Trivia: The son of an actor of the same name, Paul Guilfoyle has appeared in several major film productions, portraying a wide variety of supporting characters. He is a member of the prestigious Actor's Studio, as well as being a longtime resident of New York. He also has numerous stage credits to his name. However, the actor is best known for his role in the crime drama CSI: Crime Scene Investigation. He joined the show in its first season in 2000 as L.V.P.D Captain James "Jim" Brass, and continued to work on the show throughout the 2000s and early 2010s.

Trivia: The lithe and attractive brunette American actress Jorja Fox entered the public eye in the late '90s and early 2000s, given her involvement as a recurrent cast member in three consecutive, top-ranked U.S. television series: ER (1994), The West Wing (1999), and CSI: Crime Scene Investigation (2000). Fox is perhaps most familiar to fans of CSI, appearing in well over 150 episodes and numerous seasons.Born Jorja-An Fox on July 7, 1968, in New York, NY, but raised in Melbourne Beach, FL, Fox moved back to Manhattan in her teens and began a modeling career after winning a local modeling contest, then subsequently enrolled as a drama student at the Lee Strasberg Institute, where she studied acting under the aegis of legendary actor William Hickey (Prizzi's Honor, Forget Paris). Fox's early roles were minor and somewhat forgettable, though she debuted onscreen under the tutelage one of the finest American indie filmmakers -- Maggie Greenwald -- in that director's well-received film noir debut The Kill-Off (1991). She followed it up with an equally dark turn, as Fate 3 (alongside future West Wing co-star Allison Janney), in John Feldman's little-seen black comedy thriller Dead Funny (1995), and joined mentor Hickey and Alan Arkin for the best-forgotten Jerky Boys (1995) -- a loud, rude and obnoxious farce about a couple of prank phone callers. The film bombed with critics and the public, and disappeared instantly.Fox joined the cast of the blockbuster series ER in 1996, during its third season on the air. She played Maggie Doyle, a lesbian intern at County General Hospital who launches a sexual harassment suit against a seemingly invincible administrator. The role lasted for three seasons, wrapping in 1999; that same year, Fox signed for a supporting role on The West Wing, mega-producer Aaron Sorkin's blockbuster series drama about life in the Oval Office. Fox would spend the following years finding continued success on the small screen, most notably in the role of investigator Sara Sidle on the hit CBS series CSI: Crime Scene Investigation.

Trivia: Although bit parts in A-list features such as The Rules of Attraction (2002) and Little Athens (2005) highlight his resumé, the sandy-blonde-haired actor Eric Szmanda may find it difficult to supersede his own ties with the characterization of Greg Sanders on the top-tiered CBS series drama CSI: Crime Scene Investigation. As Sanders -- a DNA and trace expert analysis with a "nonconformist exterior" and an enduring taste for heavy metal (not to mention a deep-seated infatuation for Sarah Sidle [Jorja Fox]), Szmanda made an enduring impression among series fans, starting as a recurring character and working his way up to series regular; he stayed with the show for several years.

Trivia: After a scant few supporting roles in both Tinseltown duds (Here Come the Littles, 1985) and respected Hollywood A-listers (Michael Apted's Class Action, 1991), American actor Robert David Hall connected with his broadest fan base via his multi-season portrayal of Dr. Albert Robbins, the middle-aged coroner on the television phenomenon CSI: Crime Scene Investigation. With his portly figure, balding pate, and ever-present white beard, Hall lent a distinguished aura to his evocation of Robbins, a character with the most unusual of personal and professional histories. Off-camera, Hall is a double-leg amputee who has served for long periods as the national chairperson of the Performers With Disabilities committees of SAG and AFTRA. His career includes a long tenure as the daytime music and voice director of KNX-FM, Los Angeles. In addition to his acting role on CSI and occasional movie work, Hall made occasional guest appearances on such series as L.A. Law and The Practice.

Trivia: Known to many as Coroner "Super Dave" Phillips on the popular series CSI, actor David Berman has also appeared on the show Heroes. He's also played a recurring role on Vanished and CSI: Crime Scene Investigation.

Trivia: Louise Lombard lived and breathed the fine arts from an early age, and projected extreme versatility in many arenas. A trained dancer and actress from early childhood, Lombard graduated to television commercials by age 14, and subsequently delved into dramatic roles. Lombard evinced a remarkable predilection for emotionally and psychologically challenging evocations, such as that of a heroin addict in a PSA directed by Jon Amiel (Copycat). After gracing the BBC series Casualty and Bergerac, the ITV show Capital City, and the ITV telemovies Catherine Cookson's A Black Velvet Gown, and Perfect Scoundrels: Sweeter Than Wine, Lombard broke through to national fame in 1991, with the lead role of Evangeline Eliott in the three-season House of Eliott series on the BBC. The story concerns two sisters who travel the road from extreme poverty to wealth as proprietors of the most successful dressmaking business in all of England.For the remainder of the 1990s, Lombard sought out a series of highly individualized and intelligent projects, including Elizabeth Gill's 1997 ensemble drama Gold in the Streets (as the girlfriend of an illegal Irish immigrant) and the ITV series Bodyguards (as one of the toughs of the title). After a brief tenure as a literature student at Cambridge University (as well as studying photography and print work at St. Martin's College), Lombard spent the first decade of the new millennium branching out into more internationally oriented roles, including insurance investigator Ellen Brachman in the Dutch movie Claim (2000), and the part of Kath in My Kingdom (2001), a highly modernized adaptation of Shakespeare's King Lear. American viewers, however, will most closely associate Lombard with the romantic lead of Lady Anne Davenport in the Viggo Mortensen period adventure saga Hidalgo (2004), and the role of Dr. Harriet Fellows, a physician who assists crash survivor Alec Baldwin, in the TNT telemovie Second Nature (2003).

Trivia: HBO enthusiasts will invariably remember character actor Wallace Langham for his winning multi-season portrayal of Phil, the conceited head writer of Larry Sanders' late-night talk show, on the Garry Shandling-headlined sitcom The Larry Sanders Show. Langham (who first received billing in projects as Wally Ward) grew up in Los Angeles; his parents divorced at an early age and his mother, Sunni, designed costumes for the musical variety series Donny and Marie. Langham was, by all accounts, drawn magnetically to showbusiness; he enrolled in acting classes, signed with an agent, and landed a string of television commercials beginning at age 16 (in 1981). After high school, Langham enrolled briefly in Cal State Northridge, but dropped out after snagging a bit part in John Hughes' teenage sci-fi comedy Weird Science (1985). Scattered appearances on such series as Murder, She Wrote and Star Trek: Voyager followed -- as well as the recurring role of Josh, smart-alecky assistant to lingerie proprietor Veronica on the Kirstie Alley sitcom Veronica's Closet. It was the Shandling turn, however, that put Langham on top of his game. He made occasional feature appearances in such pictures as the Nora Ephron comedy-fantasy Michael (1996) opposite John Travolta, the Eddie Murphy vehicle Daddy Day Care (2003), the ensemble comedy drama Little Miss Sunshine (2006), the award-winning The Social Network and 2012's Ruby Sparks but -- outside of Larry Sanders -- he is probably best known for his fine work on the series drama CSI: Crime Scene Investigation. On that program, Langham sustained a multi-season portrayal as lab technician David Hodges.

Trivia: The saga of irascible and gravel-voiced actor Danny Bonaduce is archetypal and defiantly American: the child actor who scores early in his youth, bottoms out on multiple levels, and rebounds as a middle-aged man, in a slightly different celebrity role. But rarely has the tale unfolded with such color or verve.Before he reached the age of 12 (a time when most pre-adolescents are attempting to survive the rigors of elementary school), the diminutive, redheaded Bonaduce rocketed to national fame as the mischievous ten-year-old Danny Partridge on the blockbuster ABC sitcom The Partridge Family, alongside young co-stars David Cassidy and Susan Dey. His fame and success were somewhat limited, however. Though Bonaduce culled an estimated 350,000 dollars from the series, the program folded in the late summer of 1974, and the actor reportedly squandered most of his earnings not long after. Years of inactivity followed, save guest appearances on such celebrity-studded series as Fantasy Island and The Love Boat, and contributions to exploitationers such as Murder on Flight 502 (1975) and H.O.T.S (1979). The actor soon found himself battling poverty and drug addiction; a drug bust and mandatory counseling for narcotics possession followed in 1985. Bonaduce's personal life hit the skids as well; he lived with his mother well into adulthood, then married a Japanese woman, Setsuko Hattori, to help her obtain a green card, and separated from her six months later. Another drug bust ensued in 1990.Professionally, Bonaduce first caught his second wind in the late '80s, when radio personality Jonathon Brandmeier learned of his plight and staged a mock food drive to raise support for the actor. The gimmick worked; Bonaduce soon received invitations to do guest spots on numerous radio programs (including that of Howard Stern) and devised the idea of hosting an on-air slot himself. In December 1988, WEGX FM, a radio station out of Philadelphia, hired him as its late-night DJ on a call-in talk program. In time, Bonaduce moved to the midday slot on Chicago's WLUP-FM, a "personality talk" station.Bonaduce scored high ratings consistently (especially with listeners who recalled him from Family) and continued throughout the 1990s. His return to filmed entertainment began choppily and unpromisingly, with the ugly and sleazy, shoestring-budget exploitationer America's Deadliest Home Video (1992), but he soon opted for another direction -- parlaying his radio-hosting experience into a filmed, syndicated daytime talk show. Danny! premiered in 1995 and unabashedly explored the same lurid subjects as Sally Jessy Raphael and Montel Williams, but Bonaduce reeled in some critical kudos for his work. Time Magazine's Ken Tucker observed, "Danny Bonaduce is a very likable entry in a very unlikable genre. What's refreshing about the gravelly voiced redhead is that he's never pious, and he implicates his audience in the sleaze he teases." When the program folded within a few months, Bonaduce continued his radio gigs at stations in New York and (later) Los Angeles. The actor then launched yet another televised talk show, The Other Half, in 2001; a male-driven flip side to The View that he co-hosted with Dick Clark, Saved by the Bell alumnus Mario Lopez, and others, the show lasted for two years.Not long after, Bonaduce emerged yet again, as a reality TV star. Breaking Bonaduce premiered on VH1 on September 11, 2005, and pushed reality television far beyond the limits of questionable taste and ethics. The program featured calamitous episodes from the actor's home life with his second wife, Gretchen, and their two children. Low points included Bonaduce confessing his extramarital infidelity; consuming alcohol, pain killers, and steroids; verbally abusing everyone in sight; and attempting suicide by slashing his wrists (off-camera). Troubled by the actor's behavior, the producers ultimately threatened to cancel the series unless the star entered rehab; Bonaduce complied. His full rehabilitation treatment was then featured on the series. Bonaduce would continue to appear on screen, with small roles on CSI: Crime Scene Investigation and reality appearances on Re-Inventing Bonaduce and The Smoking Gun Presents: World's Dumbest.

Trivia: Tall, slender, and graceful brunette actress Sean Young has had a busy film career, but has yet to make it past mid-range stardom. This may be partially due to some of the negative publicity generated through her personal life. Before coming to Hollywood in 1980 to perform in Jane Austen in Manhattan, Young had been a New York model and a dancer. Fans of the sci-fi epic Blade Runner (1982) remember Young for playing the sympathetic "replicant" Rachael. Although she appeared in several major features by 1987, Young didn't get much notice as a potential star until after she co-starred with Kevin Costner in the thriller No Way Out (1987). Her love scenes with Costner generated considerable heat on and off the screen. In 1989, Young made entertainment news when her former co-star from The Boost (1988), James Woods, filed a harassment suit against her claiming that she had repeatedly threatened him after their affair soured. Young retaliated by hitting the talk show circuit to deny the claims, all the while continuing her acting career. That year, she was scheduled to play Vicki Vale in Tim Burton's Batman, but broke her collarbone during a riding scene with Michael Keaton and was replaced by Kim Bassinger, something she publicly disputed with Burton. Through the '90s, Young continued to appear regularly onscreen.

Trivia: North Carolina native Liz Vassey began acting on-stage when she was just nine years old, studying acting at a number of universities over the coming years before beginning her onscreen acting career. She appeared on the soap opera All My Children beginning in 1988 and would make guest appearances on numerous TV series, including Murphy Brown, Quantum Leap, and others. Soon, Vassey would be snagging staring roles on TV shows, playing roles like Captain Liberty on the cult favorite The Tick and Wendy Simms on the procedural drama CSI. Among her other credits are the supernatural series Tru Calling and the Elmore Leonard adaptation Maximum Bob.

Trivia: Attended college on a basketball scholarship. Appeared on the cover of Life magazine on May 12, 1967, with his In Cold Blood costar Robert Blake and the book's author, Truman Capote. Was offered the opportunity to join the TV series The Walking Dead, which shoots in Senoia, GA, when he was visiting Atlanta in 2011 for his mother's 97th birthday. Played Polish saint Brother Albert in Our God's Brother, a film adapted from a drama written by Karol Wojtyla, who later became Pope John Paul II and granted Wilson a private audience. Received the Exemplary Achievement Award from the Floating Film Festival in 2006. Received the Ralph Morgan Award from the Screen Actors Guild in 2007.

Trivia: Kay Panabaker, the younger sister of child actress Danielle Panabaker, actually preceded her older sibling in tackling feature roles. A wunderkind to end all, Kay grew up in the Atlanta area and discovered a love for community theater at an early age, then made a swift and easy transition to Los Angeles at the behest of her agent. She landed her first major part voicing characters for the 2001 Disney/Pixar blockbuster Monsters, Inc., and subsequently assumed countless guest roles on series programs including Angel, ER, Summerland, and CSI. Like many of her teenage and preteen predecessors, however, the young actress achieved lead status via original movies on The Disney Channel -- in vehicles such as Life Is Ruff (2005) and Read It and Weep (2006). An early and much-publicized college graduation, reportedly before the age of 18, only boosted her recognition.2007, however, marked the budding actress' breakthrough year; that fall, she realized her first theatrical lead with the issue of the feature Moondance Alexander, a National Velvet-like outing about a young lady determined to turn an ordinary horse into a champion racer, despite the objections of his curmudgeonly owner (Don Johnson). At about the same time, Panabaker tackled a supporting role in the much-anticipated cinematization of Nancy Drew, adapted from the books by Carolyn Keene. She had a small part in the remake of Fame, and went on to appear in The Lake Effect, Little Birds, and Cyberbully.

Trivia: Following her 1994 debut role as figure skater Oksana Baiul in the telemovie A Promise Kept: The Oksana Baiul Story, actress Monica Keena began to specialize in onscreen portrayals of wayward, vixenish young women. Parts that fell into this category included a lead turn in helmer Mo Ogrodnik's cloying, overbaked take of burgeoning female sexuality, Ripe (1996), and a recurring role on season two of Dawson's Creek (1998-1999) as teenage seductress Abby Morgan. As time rolled on, however, Keena broadened her focus and her emphasis into a diverse array of characterizations. Uniquely, in addition to appearing in low-medium budgeted indie films, she maintained a steady diet of roles in A-list Hollywood productions, including While You Were Sleeping (1995), The Devil's Advocate (1997), Orange County (2002), and Freddy vs. Jason (2003). She also played Kristen on the HBO seriocomedy Entourage and made repeat appearances as Bonnie on Grey's Anatomy. In 2007, Keena landed supporting roles in two promising direct-to-video features: the crime saga Loaded and the workplace comedy Corporate Affairs.

Trivia: Texan Kevin Rahm's screen-acting career started off with a number of small television guest roles before he landed a spot as a regular on the second season of the short-lived Christina Applegate vehicle Jesse in 1999. In 2001, he joined the cast of the legal drama Judging Amy and continued to appear on the show into its fifth season. Following his exit from Judging Amy, Rahm could be seen in a supporting role in the 2004 remake of Alfie, as well as several guest appearances on TV shows ranging from Grey's Anatomy to CSI. In 2007, Rahm joined the cast of ABC's hit series Desperate Housewives, staying with the series until the end, in 2012.. In 2010, he began playing the recurring role of Ted Chaough, one of the partners of the rival firm CGC on AMC's Mad Men. Rahm was promoted to a series regular in the show's sixth season.

Trivia: Was discovered at a friend's bat mitzvah celebration when a short film he performed in was seen by Steven Spielberg. Read a passage from The Catcher in the Rye during his audition for Francis Ford Coppola's Tetro. Founded The Collectin, a group of actors, directors, writers and producers that work together on films and performances, with Zoe Worth in 2009. Cast as Ethan in Beautiful Creatures when the original actor, Jack O'Connell, dropped out just before shooting began.
