Trivia: Actor Mark Harmon is the son of football great Tom Harmon and 1940s film star Elyse Knox; he is the brother of Kris Harmon -- ex-wife of Ricky Nelson -- and uncle of Kris and Ricky's actress daughter Tracy Nelson; and finally, Harmon is the husband of Mork and Mindy star Pam Dawber. Harmon emulated his dad by playing football at UCLA, then followed in mom's footsteps by turning to acting; his first movie was 1978's Comes a Horseman. Most of Harmon's starring film appearances are easy to take but unmemorable, such as his lackadaisical high-school teacher in Summer School (1988). A baseball fan, Harmon was once part-owner of the minor-league San Bernardino Spirit, a team which figured prominently in his 1988 film vehicle Stealing Home. Harmon is best known for his work on 1980s series TV: he has co-starred in Flamingo Road and Moonlighting, and played the lead role of AIDs-stricken Dr. Bob Calswell on St. Elsewhere. TV would prove to be a source of success for the actor, and he would go on to star on such popular shows as Chicago Hope and NCIS.

Trivia: David McCallum's parents were both members of the London Philharmonic; his mother was a cellist and his father was first violinist. The young Scots-born McCallum himself planned to pursue a musical career after serving with the Royal West African Frontier Force, but decided instead upon acting. Following his studies at the RADA, McCallum entered films in 1957, where he was usually cast as a troublemaking street punk or callow junior officer. His first American film (albeit lensed principally in England) was Freud (1962), in which he played a profoundly mother-obsessed mental patient. McCallum became the rage of the teeny-bopper set when he was cast as cool-headed Russian secret agent Ilya Kuryakin on TV's The Man From UNCLE (1964-68). At one point, McCallum was receiving far more fan mail than the series' ostensible star, Robert Vaughn; he took advantage of his celebrity to launch a brief singing career, duetting with Nancy Sinatra on the 1966 UNCLE episode "The Take Me to Your Leader Affair." He also wrote the music and lyrics and sang the title song of his 1967 movie vehicle Three Bites of the Apple. Following UNCLE, McCallum had a handful of solid dramatic film roles before returning to the small screen in the short-lived 1975 series The Invisible Man. He continued to appear primarily in episodic television, although he occasionally could be glimpsed on the big-screen as well. Highlights include The Watcher in the Woods, Matlock, The Wind, Murder She Wrote, and The A-Team. The nineties began with a major part in the sleeper Hear My Song, before continuing in Healer, Law and Order, and Cherry. McCallum became a fixture on television yet again at the beginning of the 21st century when he was cast as Donald "Ducky" Mallard on CBS' drama NCIS, which was for a time the top-rated scripted drama on network television.A man of sundry outside interests, McCallum's range of expertise includes computers and small-arms weaponry. Once wed to actress Jill Ireland, David McCallum has since 1967 been married to Katherine Carpenter.

Trivia: Actor Sean Murray began filling up his resumé when he was just a young teenager, making small appearances in movies like Hocus Pocus and This Boy's Life. He continued to steadily wrack up small and midsized roles in films and on television until 2004, when he joined the cast of the series NCIS playing Timothy McGee. His stepsister, Troian Bellisario, has appeared in NCIS as Murray's character's sister.

Trivia: A graduate of the famous School for the Performing Arts, actor Rocky Carroll continued his studies at the Conservatory of Theatre Arts at Webster University before moving to New York in the mid-'80s to try his hand at a professional acting career. He soon found success with the Shakespeare on Broadway series, and cultivated a flourishing career on-stage. Carroll also branched into screen acting, with recurring roles on Roc and Chicago Hope, and in movies like Crimson Tide, Born on the Fourth of July, and Yes Man.

Trivia: A graduate of Colorado's Niwot High School, actor Brian Dietzen gravitated to drama at eight years old, when he caught the acting bug from an elementary school play; in time, he extended his stage activities into high-school productions, and attended the University of Colorado at Boulder as a theater major in that institution's B.F.A. program. Under the mentorship of Sean Kelley, Dietzen formally trained in theatrical mainstays -- from Waiting for Godot to Equus; so successful were his efforts in these productions that it prompted him to join the Colorado Shakespeare Festival after graduation, and then to make the big leap to Los Angeles. Dietzen scored his first major coup in L.A. by signing on for a regular role in the short-lived WB series My Guide to Becoming a Rock Star, and then landed a small part in the American Idol spin-off movie From Justin to Kelly (2003). The actor is best known, however, for his recurring series role as Jimmy Palmer, assistant lab technician to Donald "Ducky" Mallard (David McCallum), on the popular CBS procedural thriller NCIS. On the side, he remained extremely active in stage work.

Trivia: Dropped out of college and took public speaking classes to help further her career. At the premiere of Gone (2012) she admitted she's always had a fear of being kidnapped. Was cast in NCIS in 2013 as a replacement for the departing Cote de Pablo; she was promoted to a series regular before her first episode aired.

Trivia: In his role as eager-to-fit-in exchange student Fez on the enduring and popular Fox sitcom That '70s Show, actor Wilmer Valderrama mangled the popular lingo of the eponymous decade with gleeful abandon. Though removed from his small-screen persona, the handsome actor can give the impression of a young Benicio Del Toro. His dorky and personable charm as Fez endeared him to television audiences, making him one of That '70s Show's defining personalities. Born January 30th, 1980, Valderrama is a Miami native whose family relocated to Venezuela when he was three years old; the aspiring actor would eventually return stateside to pursue a career in the entertainment industry. Valderrama joined the cast of That '70s Show shortly before finishing his high-school education at William Howard Taft High School in 1998, and three short years later, the television mainstay made his feature debut by taking to the diamond with a supporting role in the romantic teen comedy Summer Catch. Guest appearances on Grounded for Life and That '70s Show co-star Ashton Kutcher's hidden-camera prankster series, Punk'd, were quick to follow, and in 2003, Valderrama essayed the role of DJ Keoke in the flashy true-crime drama Party Monster. Based on the exploits of murderous club-kid Michael Alig, the film offered Valderrama an opportunity to truly separate himself from his popular small-screen persona. With That '70s Show still going strong in 2004, the popular television star's voice could also be heard in the animated children's film Clifford's Really Big Movie. 2006 found the actor playing a small supporting role for the scathing message movie Fast Food Nation, and took on the role of Detective Efrem Vega for the NBC television series Awake.Valderrama continued to concentrate on TV, booking guest arcs on shows like Suburgatory and Raising Hope before settling into more stable work with regular gigs on From Dusk till Dawn: The Series and the short-lived Minority Report series. In 2016, he joined the cast of NCIS for the 14th season of the show.

Trivia: Born in Pennsylvania c. 1967, Maria Bello attended Villanova University as a political science major, but acting ability - evident from an early drama class - altered her career plans. Following graduation, Bello honed her acting skills in a number of New York theater productions before she broke through to the public as one of the leads in the short-lived TV spy comedy Mr. and Mrs. Smith (1996). Bello gained broader primetime exposure as Dr. Anna Del Amico on NBC's blockbuster ER during the 1997 season and segued into films with her performance as recovering junkie Ben Stiller's confidante in the film-a-clef Permanent Midnight (1998), adapted from Jerry Stahl's harrowing book.Bello scored her first pop hit as Mel Gibson's beautiful cohort in the harsh crime drama Payback (1999). Poised to potentially become one of the select group of actors who transition smoothly from television to film, Bello co-starred as one of the bottle-tossing, bar-stomping babes in charge of the titular drinking establishment in the Bruckheimer-produced hellraiser Coyote Ugly (2000). When Coyote Ugly failed to live up to box office hopes, Bello starred as Suzi Loomis in Bruce Paltrow's Duets, and as Ruth Harkness in the IMAX feature China: The Panda Adventure (2001), based on her real-life experiences with the eponymous creatures. Bello scored a bona fide critical, if not financial, hit with Paul Schrader's biopic about slain Hogan's Heroes star Bob Crane, Auto Focus (2002). As Crane's co-star and second wife Patricia, Bello holds her own opposite Greg Kinnear's bravura performance as the nymphomaniacal Crane, evoking the complex emotions of a spouse who accepts yet ultimately cannot contend with her husband's desires.A year after Auto Focus, Bello would score even bigger with the critics with a starring role alongside William H. Macy in the gritty Vegas romance The Cooler. As the cocktail waitress who falls for Macy's sadsack ne'er-do-well, Bello brought a sense of extreme realism to her character. The film netted her a Best Supporting Actress nomination from the Screen Actors Guild and a runner-up prize from The National Society of Film Critics.In early 2004, Bello appeared as Johnny Depp's estranged wife in the Stephen King adaptation The Secret Window, and in John Sayles' well-received political thriller Silver City. Though subsequent appearances in the fairly forgettable Assault on Precinct 13, The Dark, and The Sisters followed in 2005, Bello's Golden Globe-nommed performance as an unassuming housewife who married into mystery in A History of Violence, coupled with her prominent performance as a determined alcohol lobbyist in the critically-acclaimed Thank You for Smoking, helped to get her back in the good graces of critics and end the year on a decidedly high note. When 2006 arrived, Bello joined Nicolas Cage, Michael Pena, and Maggie Gyllenhall in World Trade Center, Oliver Stone's docudrama/survival picture that recounted the experiences of two Port Authority firefighters trapped beneath the rubble of the destroyed buildings. Bello joins the cast of the same year's Flicka, adapted from the seminal children's novel by Mary O'Hara (and incarnated decades prior as the movie and TV series My Friend Flicka) , alongside Alison Lohman and country singer Tim McGraw.Bello had a lead part in Alan Ball's feature film directorial debut Towelhead in 2007, and tackled the indie horror film Downloading Nancy the next year. In 2010 she scored a small part in the Adam Sandler comedy Grown Ups as well as major parts in a couple of dramas - The Company Men and Beautiful Boy.She next returned to television, taking the lead role in the NBC remake of the British series Prime Suspect in 2011. The show was cancelled after only 13 episodes, but Bello quickly booked another television role, in the second season of Fox's Touch, opposite Kiefer Sutherland. That show was also canceled after that season, and Bello returned to film, reprising her role in Grown Up 2 in 2013.Active in social causes as well, Maria Bello co-founded the Harlem not-for-profit arts and education program, Dream Yard Drama Project for Kids.

Trivia: With the sort of GQ looks that command attention both onscreen and off, longtime actor Steven Bauer has come a long way since making an impression in Brian De Palma's controversial 1983 crime drama Scarface. A native of Cuba whose family fled to Miami shortly after Fidel Castro came to power in 1956, Bauer began his education at Miami-Dade Community College, where a walk-on role in the play Summer and Smoke sparked a lifelong love of acting. He transferred to the University of Miami and continued to hone his craft in such plays as Of Mice and Men, and by the time he moved to New York, Bauer was ready to study under the tutelage of acclaimed acting coach Stella Adler. It was during this time that auditions for Scarface were announced, and with his confidence bolstered by a handful of supporting roles in film and television, Bauer proved that he could hold his own opposite Al Pacino. Cast as the titular character's close friend and partner in crime, the young actor's powerful performance drew a Golden Globe nomination for Best Supporting Actor. Although the film's notable violence and profanity ultimately provoked a backlash from both Hollywood and the viewing public, Bauer's career maintained its upward trajectory when, the following year, the handsome rising star took the lead in the romantic thriller Thief of Hearts.Throughout the '80s, roles in such high-profile films as Running Scared (1986) and Gleaming the Cube (1989) helped maintain Bauer's presence on the big screen, but it was a role in the 1990 television miniseries Drug Wars: The Camarena Story that earned him his second Golden Globe nomination and proved he could give a commanding lead performance. Increasingly relegated to low-budget thrillers and forgettable, straight-to-video fare, he had occasional roles in such films as Raising Cain (1992) and Wild Side (1995). In 2000, Bauer shared a Screen Actor's Guild award for Best Ensemble Performance in the acclaimed Steven Soderbergh crime drama Traffic, in which the actor portrayed jailed drug kingpin Carlos Ayala. The roles that immediately followed, however, seemed to offer Bauer little room to expand his talent, though his performance in the popular, but short-lived TV series UC: Undercover at least served to keep him in the spotlight before joining an impressive cast in the 2003 Bob Dylan drama Masked and Anonymous. Married to actress Melanie Griffith for the majority of the '80s, the couple divorced in 1987. Bauer married Ingrid Anderson in 1989.

Trivia: Pam Dawber grew up in Detroit, where her father was a commercial artist and her mother ran a stock-photo agency. Blessed with a four-octave soprano voice, Dawber prepared for a singing career while attending Oakland Community College. After suffering the traditional setbacks, she began working as a model in New York. This led to a string of commercials, including one of the early "Tupperware Lady" musical ads. In 1977, she made her first film appearance in Robert Altman's A Wedding, making an unforgettable entrance on horseback. The following year, she was cast as Mindy McConnell on the weekly Robin Williams sitcom Mork & Mindy. Though Dawber was generally relegated to straight woman and sounding board for Mork's zany antics, Williams did his utmost to see that his co-star was given a few isolated moments to shine. After Mork & Mindy ended its four-year run, Williams went on to theatrical features, while Dawber busied herself in made-for-TV movies. In 1986, she was top-billed in another successful TV comedy, My Sister Sam, which came to an abrupt end in 1988 when her co-star, Rebecca Schaeffer, was murdered by a crazed fan who was stalking her. Since that time, Dawber has appeared on-stage and in a handful of films, including the much-delayed fantasy Stay Tuned (1992), in which, courtesy of animation director Chuck Jones, she was briefly glimpsed in cartoon form. She has also been active as national spokesperson for Big Brothers and Big Sisters of America. Pam Dawber is married to actor Mark Harmon.

Trivia: Going under the name Pauley P., actress Pauley Perrette (born March 27th, 1969) first gained notoriety with an extended arc on the acclaimed ABC drama Murder One. She followed that with guest spots on such shows as The Drew Carey Show and Frasier before landing a gig as a regular (using her full moniker) on the short-lived Party of Five spin-off Time of Your Life. After that series bowed, Perrette could be seen in small capacity in the big-screen hits Almost Famous and The Ring. In 2003, she finally landed in a series with staying power. This time it was the JAG spin-off Navy NCIS, a CBS drama that cast Perrette in a lead role alongside Mark Harmon.

Trivia: Born in New York City on August 8th, 1968 and raised in Fairfield, CT, prolific film and television actor Michael Weatherly got his start on an episode of The Cosby Show before moving on to carve out an impressive career on screens both large and small. While many television viewers would recognize Weatherly from walk-on roles in such popular television series as Charmed and Ally McBeal, it was the actor's controversial age-disparity romance with Dark Angel co-star Jessica Alba that got tongues wagging around Tinseltown back in 2001. He could be seen opposite Alba on that sci-fi program throughout its two-season run (2000-2001). Later, Weatherly portrayed actor Robert Wagner in the made-for-television drama The Mystery of Natalie Wood before revealing a deeply personal secret about his onscreen girlfriend in Her Minor Thing. In 2003, Weatherly landed his most regular television role to date, as a Naval criminal investigator on NCIS.

Trivia: Born in Chile but raised in Miami, actress Cote de Pablo developed an impressive resumé on both stage and screen. In 2001, she appeared in a New York City Public Theater production of Measure for Measure, and in 2005, she made her Broadway debut in The Mambo Kings. In 2006, she joined the cast of the series NCIS, playing Mossad operative Ziva David. She made her big-screen in the western The Last Rites of Ransom Pride.

Trivia: American actress Lauren Holly has herself admitted that turning down the female lead in the Jim Carrey vehicle Ace Ventura, Pet Detective (1994) may not have been the wisest career move. Holly was acting on instinct, having co-starred with another highly individual comedian, Andrew Dice Clay, in 1990's forgettable The Adventures of Ford Fairlane. But when profits from Ace Ventura soared, Lauren was more than willing to sign on for the subsequent Carrey vehicle, Dumb and Dumber (1995), during the filming of which she and Carrey became an item. The actress has kept busy ever since her first important TV role as Betty in Archie: To Riverdale and Back Again (1990) and a stint on the ABC soap opera All My Children. Prior to her recent film success, Holly was perhaps best known for her role as Deputy Maxine Stewart on the CBS drama Picket Fences .In 1995 the actress played a doctor in Sydney Pollack's remake of Sabrina, and went a different direction in 1996's comedy Down Periscope, in which she played Lieutenant Emily Lake. Holly took on a supporting role in Any Given Sunday (1999), a rousing sports drama from director Oliver Stone, and joined Mel Gibson and Helen Hunt to play a supporting role in 2000's romantic comedy What Women Want. The following year Holly would voice Chihiro's mother in the US rerelease of the acclaimed anime fantasy Spirited Away the following year, and from 2005 until 2008 became known for her role as Director Jenny Shepard on CBS' long-running police procedural NCIS. Holly voiced the character of Haulie on the Adventures of Chuck & Friends, an animated series for children in 2010, and continues to be active in film and television.

Has appeared in commercials for Microsoft, Burger King, Sprint and AOL. Studied ballet, jazz, lyrical and tap dance.

Trivia: While other students at Berkeley were weaving flowers in their hair and blowing weed, Joe Spano was laying the groundwork for an acting career. After establishing himself on the San Francisco theatrical scene, Spano began showing up on screen in such supporting roles as Vic in American Graffiti (1974) and Ace in Roadie (1980). From January 1981 through May 1987, Spano could be seen on a weekly basis as Henry Goldblume, the bespectacled and bowtied community affairs officer on the TV series Hill Street Blues. In 1992, Joe Spano made his Broadway debut in a revival of Arthur Miller's The Price.

Trivia: Los Angeles native Sasha Alexander honed her interest in acting with roles in school plays, but soon graduated to a professional career with roles on shortlived series like the drama Wasteland and the wild comedy Greg the Bunny, on which she shared an on-screen kiss with comedian Sarah Silverman. In 2003, Alexander took on the role of Agent Caitlin Todd on the series NCIS. She would play the role for many seasons to come, in addition to roles in movies like Yes Man and Love Happens, and other TV shows, like Rizzoli & Isles.

Trivia: The adorably spunky Amanda Detmer had everyone going when she took on teen roles, bright-eyed and genuine, in films like Boys and Girls and Final Destination. Indeed, the actress in real life was substantially older than the young women she portrayed onscreen, although her convincingly youthful performances aided her looks in deceiving viewers about her age. Born on September 27, 1971, in Chico, CA, Detmer's academic career was established long before her successful list of film credits. After attending California State University as an undergraduate, she earned her master's degree at N.Y.U. in fine arts. While her acting debut occurred with the television movie Stolen Innocence in 1995, she decided to complete her M.F.A. before seriously embarking on a career in show business. In 1999, she re-entered the dramatic scene with a role in the TV miniseries To Serve and Protect. She also gained exposure and television experience on the series MYOB and Ryan Caulfield: Year One. Finding an asset in her youthfulness, she then appeared in two teen films, despite being in her late twenties, in 2000: Boys and Girls -- a romantic comedy starring Freddie Prinze Jr., Claire Forlani, and Jason Biggs -- and the thriller Final Destination. Upon gaining attention in Hollywood, she was often found in warm and lighthearted roles, if not in outright comedy, as appropriate for the sweet charm her presence evokes onscreen. She starred as a would-be nun, longed for by the character played by Jason Biggs in Saving Silverman (2001), also featuring Jack Black. In The Majestic (also 2001), she portrays the woman Jim Carrey leaves behind when stricken with amnesia. In addition to smaller roles in 2002's Kiss the Bride and Big Fat Liar, she would star in a comedy by Lorena David entitled Extreme Dating. An action-packed romantic adventure, the film also starred Devon Sawa. Though Extreme Dating may have thrown a little something original in the romantic comedy mix by offering a little more gunplay and adrenaline than the typical chick flick, few of Detmer's efforts in the following years would prove adventurous or original enough to really break the mold or merit mentioning. A key role on the small-screen relationship drama What About Brian offered the actress a bit more to chew on in 2006, and later that same year Detmer could be seen in the Owen Wilson houseguest-from-Hell comedy You, Me, and Dupree. Over the coming years, Detmer would appear in a number of other projects, including the series What About Brian, Private Practice, Man Up, and Necessary Roughness.

Trivia: Named as the back stage's most memorable NY Stage performance for her role as Miss Price in the Broadway play Coram Boy in 2007. Played the role of Miss Qian in the Broadway play Chinglish in 2011. In 2013, made a guest appearance in Grey's Anatomy's season finale episode. Winner of the Earphones award for the audiobook Do Not Say We Have Nothing.

Trivia: Aspired to be an actor from the age of 5. Moved to London at the age of 17 to pursue his acting career. Was homeless for a short time while searching for work as an actor. Appeared in numerous British television series, including Law & Order: UK, Doctor Who, The Cut and Doctors. Nominated for BAFTA's Screen Nation Award for Best Emerging Talent in 2010. In 2013, moved to Los Angeles in hopes of furthering his acting career. Starred in a 2015 TV commercial for Lexus.

Trivia: A budding TV star, Jennifer Esposito (born April 11th, 1973) opted to focus more exclusively on movies after landing one of the lead roles in Spike Lee's incendiary Summer of Sam (1999). A native New Yorker, Esposito trained at the Lee Strasberg Institute and worked on TV in the early 1990s, including a recurring role on New York Undercover. Following small roles in indie films Kiss Me, Guido (1997) and A Brother's Kiss (1997), Esposito gained prime time notice in 1997 as Michael J. Fox's sassy "Noo Yawk" secretary on ABC's hit sitcom Spin City. During her two seasons on the show, Esposito also appeared in Edward Burns' blue collar romance No Looking Back (1998), the teen slasher sequel I Still Know What You Did Last Summer (1998), and Spike Lee's basketball drama He Got Game (1998). After playing the more substantial dramatic part of Adrien Brody's punk singer girlfriend in Summer of Sam, however, Esposito left Spin City in 1999. Dividing critics and audiences over its dicey slice of New York City 1977 life and Lee's visual pyrotechnics, Summer of Sam failed at the box office. Esposito next appeared as one of Chris O'Donnell's ex-girlfriends in The Bachelor (1999). The millennial turnover found the beautiful rising starlet establishing herself as a versatile actress in such efforts as Dracula 2000 (2000) and Don't Say a Word (2001), and after appearing alongside Dana Carvey in the family comedy The Master of Disguise (2002), Esposito joined an impressive cast including Luis Guzman, William H. Macy and George Cloony for the caper comedy Welcome to Collinwood (also 2002). In 2004, Esposito took on a role as the long-suffering supervisor of a bumbling police officer in the less than successful comedy Taxi. The following year, however, her luck would change when she joined the cast of filmmaker Paul Haggis' Academy Award-winning drama Crash, in which she played the girlfriend and partner of an emotionally distant police officer. Afterwards, the actress joined several television shows including FX's drama Rescue Me, in which she worked alongside the show's star Denis Leary, and also appeared in ABC's comedy Samantha Who?, NBC's medical drama Mercy and CBS's cop procedural Blue Bloods.
