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: 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: 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: 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.

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.

Trivia: Best known for portraying time traveler Dr. Sam Beckett in the popular sci-fi series Quantum Leap, Scott Bakula is also a noted Broadway actor and occasional movie star, though it is in the last venue that he has had the least amount of success. The son of a musician, Bakula is said to have started his own rock band when he was in the fourth grade. He also sang with the St. Louis Symphony before attending the University of Kansas. Bakula launched his acting career as a teen in regional theater and as a stage actor specializes in musical comedy. He made his Broadway debut in 1983 in Marilyn: An American Fable. He started showing up regularly on television as a guest star on such series as My Sister Sam and Designing Women during the 1980s. In 1986, Bakula starred in an unsuccessful television series, Gung Ho! Two years later he headlined another unsuccessful one, Eisenhower and Lutz.

Story (1991) and My Family/Mi Familia (1995). In 1993, Bakula had a recurring role on the CBS sitcom Murphy Brown as a love interest of Candice Bergen. He has also appeared in a number of television movies and in 1996, he had a stint in another short-lived series, Mr. and Mrs. Smith.Though he worked steadily in movies, television turned out to be his next great success when, in 2001, he took the part of Capt. Jonathan Archer on Star Trek: Enterprise, a program that lasted four seasons.In 2009 Bakula would star alongside Ray Romano and Andre Braugher in the well-respected comedy/drama series Men of a Certain Age, and landed in one of the best films of his career, Steven Soderbergh's The Informant!.

Trivia: Though he has proven to be a natural, allegedly Lucas Black's ambition is not to be an actor when he grows up. Born and raised in Alabama, Black became a professional actor when an open casting call landed him a bit part in Jon Avnet's The War (1994). After starring on TV's American Gothic (1995), Black definitively caught the audience's attention with his pivotal role in Billy Bob Thornton's award-winning drama Sling Blade (1996). Resisting child actor treacle, Black turned in a genuinely charming and moving performance as the young boy who befriends Thornton's mentally challenged ex-con. Despite the acclaim, however, Black opted to stay home in Alabama rather than go Hollywood. Black continued to act throughout his high school years, playing supporting roles in the racial drama Ghosts of Mississippi (1996) and the big-screen version of The X-Files (1998), and starring in the TV movie Flash (1997) and as the politically aware Peejoe in Crazy in Alabama (1999). In Thornton's second directorial effort All the Pretty Horses (2000), Black's performance as the young drifter who gets Matt Damon into trouble once again revealed his ability to hold his own against -- indeed outshine -- Hollywood's best. Black, however, has asserted that his ultimate goal is to become a professional fisherman. High profile roles as everything from a piano savant in Killer Diller to a high school football star in Friday Night LIghts and a fresh-faced Marine in Jarhead proved without question that Black had the acting range needed to craft and impressive and enduring career, and in 2006 Black put the peddle to the metal as a troubled teen whose trip to Tokyo finds him mastering the art of the drift in the adrenaline-charged sequel The Fast and the Furious: Tokyo Drift.

Trivia: After a string of guest roles on TV and bit parts in movies, actress Marisol Nichols gained prominence as the lead in the 2001 made-for-television romantic drama The Princess and the Marine. Playing an Arab princess who falls in love with an American Marine, Nichols delivered a performance that earned her the Outstanding Actress in a Made for Television Movie or Miniseries prize at the 2002 American Latino Media Arts Awards. More supporting roles on TV followed until 2005, when Nichols landed the female lead opposite Ron Eldard on the Steven Bochco-produced cop show Blind Justice.

Trivia: Possessing a dark but earthy beauty and a natural, winning smile, actress Rena Sofer has found notable small-screen success in such series as Melrose Place, Just Shoot Me, and Coupling after spending the majority of the 1990s in an Emmy-winning role on the daytime soap opera General Hospital. As the millennium turned, so did Sofer's cinematic aspirations, with keen-eyed movie lovers spotting her in such feature efforts as Traffic (2000) and March (2001). An Arcadia, CA, native, Sofer relocated to Pittsburgh when her Orthodox Jewish rabbi father and psychology teacher mother divorced. Spotted by a New York talent agent at the age of 15, it wasn't long before Sofer was appearing on the daytime drama Loving and landing roles on such small-screen efforts as Herman's Head and Saved by the Bell: Hawaiian Style. In 1992, she made her big-screen debut with a small role in Sidney Lumet's A Stranger Among Us with Melanie Griffith. Beginning a four-year run on General Hospital in 1993, Sofer would simultaneously appear in numerous made-for-television features before beginning her year-long run on Melrose Place in 1998. She made a notable leap back to the big screen with a small role in the 2000 comedy Keeping the Faith, and after following up with Traffic, Sofer settled back into sitcom life with a high-profile guest-starring role on Ed. In the 2002 made-for television remake of Carrie, her part as a sympathetic high school teacher proved a highlight of the otherwise forgettable effort, and in 2003, she headed the cast of Coupling, the highly anticipated American remake of the popular U.K. sitcom.

Trivia: Actress Lindsay Price began her career when she was just a little girl, appearing in commercials including a Toys "R" Us ad in which she sang the toy store's famous jingle. Price eventually grew into a young woman, attending the Art Center College of Design in Pasadena, CA, but her interest in appearing onscreen only grew. She began making appearances on shows like Boy Meets World by the time she was 17 and two years later, in 1995, she scored a recurring role on the soap opera The Bold and the Beautiful. Then, in 1998, she joined the cast of the night-time drama Beverly Hills 90210, which was beginning its tenth season. She brought a new, fresh energy to the series, leading to a string of appearances over the next few years, including a starring role on the American remake of the British series Coupling, as well as roles on Pepper Dennis and Lipstick Jungle. In 2009 she was cast in the short-lived TV series Eastwick, based on the popular novel and film The Witches of Eastwick. After welcoming a son with chef Curtis Stone in 2011, Price slowed down her acting work, though she still appeared in occasional guest spots on shows like Two and a Half Men and Hawaii Five-0.

Trivia: The daughter of film stars Tony Curtis and Janet Leigh, Jamie Lee Curtis launched her film career as a "scream queen." After a nondescript supporting role on the TV series Operation Petticoat, Curtis rose to cult stardom playing the straight-laced teenage babysitter imperiled by an unknown slasher in Halloween (1978). Upon appearing in the film's sequel and in such spookers as The Fog (1979) and Prom Night (1980), she seemed in danger of being limited to blood-splattered horror films. But Curtis wasn't about to be typed this early in the game: with a meaty secondary role as a prostitute -- featuring several well-publicized nude scenes -- in the big-budget comedy Trading Places (1983), she made the transition from imperiled teen type to knowing adult with nary a hitch. Curtis didn't exactly have a string of box-office smashes after Trading Places, but she was always worth watching even when the films weren't. And when the good parts did come along, notably her roles in A Fish Called Wanda (1988) and My Girl (1991), she proved she was an actress of range and stature and not just another "movie star's kid." Taking a potentially humiliating role as the unknowing wife of a secret agent in the megabucks Arnold Schwarzenegger adventure True Lies (1994), Curtis delivered a sparkling performance, emerging as the only truly likable character in a loud and misogynistic melodrama. In 1997, she was reunited with the cast of A Fish Called Wanda (Kevin Kline, John Cleese, and Michael Palin) for Fierce Creatures, another comedy farce in the same vein as Wanda. Unfortunately, the film was largely disappointing; but, the following year, Curtis rebounded with a return to familiar territory in Halloween: H2O. The slasher flick, although less than a critical favorite, proved to be popular with audiences. In 1999, Curtis again ventured into the big-budget realm with the action thriller Virus, and had a supporting role in Daddy and Them, Billy Bob Thornton's sophomore writing/directorial effort. She could then be seen in Drowning Mona, a black comedy in which she played a waitress caught up in an affair with the husband of her town's most infamous dead woman.The 2000s have brought Curtis several interesting opportunities, including a live performance at Paul McCartney's benefit for the controversial animal rights organization PETA in 2000, and a no-holds-barred photo shoot with More magazine in 2002 -- the then 44-year-old actress wanted to emphasize that even high-profile celebrities look "normal" without the help of a team of makeup artists and digital alterations. In 2001, Curtis starred alongside Oscar-winner Geoffrey Rush and James Bond front man Pierce Brosnan in the espionage thriller The Tailor of Panama, and returned for a cameo appearance in Halloween: Resurrection, which supposedly marked her final role in the Halloween franchise. Curtis would return to more family-oriented pictures in 2003's spirited Freaky Friday with Lindsay Lohan, which featured the forty-something actress playing a punky teen whose spirit had magically been transferred to her mother's body; the success of that film led to the curdled comedy of the critically drubbed Christmas With the Kranks. She acted in Beverly Hills Chihuahua and You Again, but became better known in later years as a spokeswoman for Activia yogurt.Married to actor Christopher Guest since 1984, Curtis became a Baroness, Lady Haden-Guest, when her husband inherited the Barony in 1996.
