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: 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: Forget "ingenue" -- by the time the glamorous Diane Farr arrived on set for her first major filmed assignment, with her sun-drenched brunette hair and photogenic Mediterranean complexion, she already qualified as an old pro in the talent realm, as a veteran model from her preteen years. Though her official acting resumé dates back to 1992, Manhattan-born Farr first culled national recognition six years later, as a hostess of the television series Loveline, a somewhat frank spin-off of a popular radio program in which viewers could phone in and ask the hosts questions about health and/or relationships. After a series of occasional turns in low-profiled TV series and telemovies, Farr landed a string of semi-permanent roles on popular small-screen series. She began with the blockbuster sitcom The Drew Carey Show (in 1999). As Tracy -- the object of multiple affections from Drew, Lewis (Ryan Stiles), and Oswald (Diedrich Bader) -- Farr unwittingly instigated a series of cutthroat competitive games among the boys, including her own sporting event, christened "The Tracy Bowl" and announced by broadcaster Bob Costas. The Tracy characterization lasted a short time, but it marked only the beginning of a seemingly unending line-up of roles for Farr. Between 2001 and 2002, she starred as gutsy female police detective Jan Fendrich in the critically praised but all-too-short-lived Denis Leary cop dramedy The Job. Two years after that, Farr worked for director Barnet Kellman in Like Family (2003), a short-lived sitcom about a black family and a white family attempting with great strain to live under the same roof together harmoniously. In 2005, Farr scored critically and commercially as FBI agent Megan Reeves on the detective program Numb3rs, starring David Krumholtz, Rob Morrow, and Judd Hirsch. Carr joined the cast of HBO's Californication in the show's first season, and appeared in Buried (2010), a well-received psychological thriller following a truck driver who becomes trapped underground.In addition to her acting work, Farr is also a published author. Her first novel, The Girl Code, found a considerable audience, and she has penned articles for numerous women's magazines. In addition to her acting and writing work, Farr co-founded and operates a greeting card firm.

Trivia: Kansas native Tuc Watkins built a career acting on daytime soap operas with two multi-year runs on One Life to Live, as well as extended stints on General Hospital and All My Children. In 1999, he was cast as the lead on the Showtime original series Beggars and Choosers, which was an edgy drama about the TV industry and lasted two seasons. Watkins' first major prime-time network role came in 2007 when he scored a role on ABC's hit comedy drama Desperate Housewives, playing one half of Wisteria Lane's first gay couple. In the years to come, Watkins would remain active on screen, making guest appearances on shows like Parks and Recreation and Franklin and Bash, while continuing his regular role as David Vickers on One Life to Live.

Trivia: The daughter of actor Will Geer, Ellen Geer began her own stage career in the early 1960s. Among Ellen's first film roles were a nun in Richard Lester's Petulia (1968). and a hippie named Sunshine in Hal Ashby's Harold and Maude (1971). In 1971, Geer appeared as a regular on the brief TV sitcom The Jimmy Stewart Show, playing Stewart's daughter. Three years later, she co-starred with her father in the theatrical feature The Silence (1974), and also collaborated on the screenplay. Ellen Geer's more recent credits include the part of Rose in Patriot Games (1992) and its sequel, A Clear and Present Danger (1994).

Trivia: Auburn-haired actress Larissa Laskin specialized in polished types with more than a passing veneer of class and sophistication and frequent professional aspirations. She made her first appearances during the early '90s, on such syndicated series programs as My Secret Identity and Kung Fu: The Legend Continues, and by the tail end of that decade she was a mainstay in telemovies including Mario Puzo's The Last Don II (1998) and Ricky Nelson: Original Teen Idol. Laskin took one of her earliest big-screen bows as a physician in the A-list feature John Q. (2002), starring Denzel Washington and James Woods; at about the same time, she also frequently appeared in popular TV series including Body and Soul (as a cast regular) and CSI: Crime Scene Investigation (as a guest star). Laskin also participated in the critically derided and stillborn sketch comedy revue The Onion Movie (2005), and signed for a small supporting role opposite Stephen Dillane and Rosamund Pike in the psychological drama Fugitive Pieces.

Trivia: Onscreen performer Jennette McCurdy launched her acting career as a child star in the early 2000s. She subsequently divided her time between supporting roles in made-for-television features, such as the 2004 Tiger Cruise and the 2007 Last Day of Summer; guest-star assignments on series programs including Malcolm in the Middle, CSI, and Will & Grace; and occasional bit parts in theatrical features. McCurdy ascended several notches in terms of billing when cast as one of the leads on the Nickelodeon cable series iCarly in 2007. The program concerns Carly, a young woman (Miranda Cosgrove) who runs a regular Internet webcast with two of her friends (played by McCurdy and Nathan Kress). In the years to come, McCurdy would appear in movies like Minor Details.

Trivia: An English major in college, Ed Lauter worked as a stand-up comic before entering films in 1971. The tall, menacing Lauter has generally been typecast as humorless, easily corruptible authority figures. He was at his meanest as the vindictive Captain Knaur in Robert Aldrich's The Longest Yard. His TV credits include such roles as Sheriff Cain in BJ and the Bear (1979-80) and General Louis Crewes in Stephen King's The Golden Years (1991). In 1976, Ed Lauter was afforded a rare leading role--and a sympathetic one to boot--in the made-for-TV murder mystery Last Hours Before Morning (1976). Lauter appeared in the 2005 remake of The Longest Yard and had a small role in the Oscar-winning film The Artist (2011). He also had a recurring role on the TV series Shameless. Lauter passed away in 2013 of mesothelioma at age 74, with several films in post-production, awaiting release.
