Trivia: A woman who unquestionably owes her dark, sensual allure to her Croatian ancestry, Canadian actress Stana Katic achieved fame with multi-episode appearances on the prime-time cop drama The Shield, the hit counterterrorism thriller 24, and the popular serial drama Heroes (as Hana Gitelman, a character who can wirelessly connect to and interact with the Internet using only her mind). Katic scored her first big-screen coup in 2007 when she was cast as Jenny in legendary writer/director Robert Benton's gentle ensemble drama Feast of Love. She landed a part in the James Bond film Quantum of Solace in 2008, but it was 2009 when she landed a leading role on Castle, a series that built a loyal following. She parlayed the show's success into parts in the feature films For Lovers Only, Truth About Kerry, and The Double.

Trivia: Born in Alberta, Canada, in 1971, Nathan Fillion took his acting ambitions to the United States when he moved to New York in 1994 to portray Joey Buchanan on the ABC soap opera One Life to Live. Having previously appeared in a single TV movie, Ordeal in the Arctic, Fillion's acting career had taken a backseat to his plans to be an English teacher. His three-year stint on the long-standing daytime TV staple, however, changed his focus in a big way. When his time on One Life to Live was up, the 27-year-old actor relocated to Los Angeles to assume a regular role on the sitcom Two Guys, a Girl, and a Pizza Place. Shortly afterward, he made a memorable appearance as the "wrong Ryan" in Steven Spielberg's WWII epic Saving Private Ryan. He also made appearances on The Outer Limits, King of the Hill, Pasadena, and other projects. It was in 2002, however, that he assumed the role that would make his career. Buffy the Vampire Slayer creator Joss Whedon selected Fillion to portray rugged captain Mal Reynolds for his new sci-fi/Western series Firefly. The show found a rabidly loyal cult fan base, as well as incomparable critical praise, but tragically, failed to find the wide audience that Fox had been hoping for. The show was canceled after only 11 episodes, but Fillion had reached a level of familiarity with the public that most actors never hope to achieve. He reprised the role of Mal in 2005 for the feature-film adaptation of Firefly, Serenity, to the delight of fans. In 2006, Fillion stayed on the cream of the fringe with the much anticipated horror film Slither. Starring alongside Elizabeth Banks, the actor stole the show with his humorous, low-key performance. For his next project, he signed on to act alongside Keri Russell in the romantic comedy Waitress. When the writer's strike hit, Fillion teamed with his old collaborator Joss Whedon to star in the direct-to-the-web musical miniseries Dr. Horrible's Sing-Along Blog. In 2009 he landed the title role on the ABC series Castle, and took a small role in the dark superhero comedy Super in 2010.

Trivia: Susan Sullivan is an Emmy-nominated actress who has proved equally adept at drama or comedy. She is best known for her eight years portraying Maggie Gioberti on the television series Falcon Crest, a prime-time network soap opera in a vein similar to that of Dallas and Dynasty, but she has also shown her comedic skills on sitcoms such as It's a Living and The George Carlin Show. Born Susan Michaela Sullivan in New York City in 1942 (some sources say 1944), she put herself through college by working as a Playboy bunny in the early '60s. Indeed, Sullivan was among the first Playboy bunnies employed by the newly opened Playboy Club in New York; as she has recalled in interviews, this was a most intellectually impressive and ambitious array of women, somewhat different from what the Playboy bunnies subsequently became, many of them aspiring to careers in law and other professions, and financing their educations by working at the club. Her television career began when she joined the cast of the daytime drama Another World in the role of Lenore Curtin, who she portrayed for four seasons. Sullivan based her career in New York, and was appearing in an off-Broadway play when she was spotted by an agent who offered to represent her if she moved to Hollywood. She accepted and thus began her career in prime-time television. Sullivan (who was sometimes billed as Susan J. Sullivan early in her career to distinguish her from another late-'60s actress named Susan Sullivan) appeared on television series such as Medical Center, McMillan & Wife, Kojak, and Petrocelli during the early '70s before landing the role that would establish her acting credentials, as Peter Strauss' lover in Rich Man, Poor Man--Book II (1976), which earned her an Emmy nomination. That same year, she moved into feature films, playing opposite Charlton Heston in Jack Smight's feature film Midway; she only had ten minutes of screen time in the movie, but hers were some of the best and most dramatically involving scenes in a movie that was otherwise largely devoid of character development or depth. Her sequences were used exclusively for the two-part television version of the movie, which means that theatrical audiences never saw her; Sullivan's scenes were missing from every home video version of the film until the October 2001 DVD reissue of Midway, which contained her footage. She spent most of the rest of the '70s in good guest-starring roles on series such as Taxi (where, in the episode "What Price Bobby," she proved herself capable of getting laughs and being sexually provocative at the same time, portraying an amorously predatory theatrical agent), and she turned in an exceptional dramatic performance in the pilot film for The Incredible Hulk, portraying a research scientist and friend of stricken hero David Banner (Bill Bixby). Her star continued to rise when she was cast in the lead role, as a gynecologist, in the made-for-television feature Having Babies and a sequel, which led to Sullivan playing the lead role in the subsequent ABC network series of the same name. From there, she was cast in the sitcom It's a Living, playing the most mature and sensible member of a group of waitresses at an upscale restaurant. It was after leaving It's a Living in 1981 that Sullivan earned the lead role of Maggie Gioberti on the drama Falcon Crest, which she played for eight seasons. Since leaving that series in 1989, a year before the end of its run, Sullivan has continued to act in both comedy and drama, and appeared on television on behalf of various charitable causes, as well as serving as the commercial spokesperson for Tylenol. She was a co-star on the George Carlin Show and has appeared on sitcoms such as Dharma & Greg. In the 2st century she found a regular gig voicing Hippolyta on the animated Justice League series, and enjoyed recurring roles on both The Drew Carey Show and Castle.

Trivia: Started dancing and gymnastics lessons at age 3. Starred in a series of local commercials and print ads in her youth. At age 6, she performed in a local ballet production of The Nutcracker. Took acting classes from retired director/producer Martin Beck. Was discovered by director Linda Seto at a summer film camp in Dallas, TX, and was encouraged to move to Los Angeles. Made film debut in a bit part in the 2007 comedy Walk Hard: The Dewey Cox Story.

Trivia: Actress Tamala Jones launched her career as a model, appearing in magazine ads and television commercials, before landing her first acting job on an episode of the preteen sitcom California Dreams, but her interest in the craft goes back to early childhood, when Jones and her cousin would stage backyard shows. Los Angeles-born and raised, Jones first studied drama in the sixth grade. As a young woman, she guest starred on series ranging from The Fresh Prince of Bel-Air to E.R. to The Wayans Brothers. She had her first regular television role playing a student in the ABC network's short-lived drama Dangerous Minds. Jones entered feature films with a small role in How to Make an American Quilt (1995) and had her first starring film role in Booty Call (1997). In 1998, Jones starred in the short-lived NBC summer replacement sitcom For Your Love. After appearing in Blue Streak and The Wood the following year, Jones began to gain even more momentum in 2000 with roles in Ice Cube's Next Friday and the Tim Meadows SNL vehicle The Ladies Man. Jones would later share the limelight with a talented cast in Kingdom Come in 2001. She continued to work steadily in a variety of projects including Head of State, Daddy Day Camp, Who's Your Caddy?, and What Love Is before being cast on the television show Castle as Lanie Paris. In 2010 she starred in and co-produced the romantic comedy 35 & Ticking.

Trivia: Started acting when he was 10 years old. First became known for his role as Antonio on the television series Moesha. Spent eight years in the military and participated in Operations Just Cause and Desert Storm. Finished a college degree in theater while in the Air Force. Nominated for a 2000 ALMA Award for his role on ABC's Sabrina the Teenage Witch. Has worked closely with several charities that help veterans, including the Wounded Warrior Fund and Puppies Behind Bars.

Trivia: Is the son of a drama teacher. Has been in more than 50 plays, and is well known for his stage work in the Los Angeles area. Did voice-over work in the 2002 Activision video game Soldier of Fortune II: Double Helix. Has had many guest roles on numerous television shows, including CSI: Miami, Close to Home, Crossing Jordan, Charmed, JAG and Cold Case. After his General Hospital character, Dr. Ian Devlin, was killed off, he went on to play another doctor, Dr. Chris Ferlinghetti, on Army Wives.

Trivia: Appeared with stage and screen legend Ruby Dee in a 2001 off-Broadway production of Bridgette Wimberley's Saint Lucy's Eyes.

Has written for and acted in a Web series called Callbacks, produced by Unlimited Ceiling, a company she cofounded with Seth Yaitanes.

Trivia: Although she officially launched her dramatic career on the big screen, with bit parts in Jonathan Demme's nostalgic period piece Swing Shift (1984) and Wes Craven's gore picture The Hills Have Eyes, Part II (1984), African-American actress Penny Johnson (also occasionally credited by her full married name, Penny Johnson Jerald) gained broadest recognition as a network mainstay on innumerable short-lived and long-running U.S. television series. Her presence on the glitter box quickly became so widespread, in fact, that devoted prime-time viewers who fail to connect with Johnson's name will invariably identify her countenance.Born March 14, 1961, in Baltimore, MD, Johnson recognized acting as her life's work while a teenager, and subsequently commenced dramatic training at her home city's Centre Stage Theatre, at age 13, by lying about her age to get in. (She claimed to be 14 -- the ensemble's minimum age requirement.) The ruse worked, and Johnson's success with that troupe encouraged her to subsequently perform in a traveling ensemble (as a mime, juggler, and fire eater) with the Baltimore-based Theatre Project, and attend university for dramatic training at Juilliard several years later. After the aforementioned film roles, Johnson segued into television, first with a brief ongoing role as Debbie on the daytime soap General Hospital (in 1986), then as university law student Vivian on the Showtime pay cable service's revival of the late '70s CBS series The Paper Chase, retitled The Paper Chase: The Second Year (a role she sustained from 1984-1986). After guest spots on such programs as The Jeffersons, Simon & Simon, and Tour of Duty, Johnson landed one of the leads on the very short-lived ABC sitcom Homeroom -- starring as Virginia "Vicki" Harper, the medical-student wife of adman-turned-fourth grade teacher Darryl Harper (Darryl Sivad). That program premiered on September 24, 1989, and wrapped not three months later, unable to find an audience.Johnson then re-teamed with Craven for the director's telemovie Night Visions (1990), about a tough L.A. cop (James Remar) who solicits the help of a psychic (Loryn Locklin) to root out a serial murderer. Craven and co. shot that effort as a pilot for a prospective series, but it never took off. In 1992, the actress returned to pay cable by joining the cast of The Larry Sanders Show, comedian Garry Shandling's HBO satire about the behind-the-scenes shenanigans at a late-night, Carson-style talk program. Johnson struck gold with that move; the show lasted until 1998 and became a massive runaway hit and a critical darling.After small turns in two A-list cinematic releases -- 1993's Tina Turner biopic What's Love Got to Do With It? (as Lorraine) and Rusty Cundieff's 1994 gangsta rap satire Fear of a Black Hat (as Re-Re) -- Johnson carved a permanent niche for herself on three number-one television series, sequentially Star Trek: Deep Space Nine, ER, and 24. In the first, she played Kasidy Yates, a stunningly gorgeous freighter captain who meets and falls in love with Benjamin Sisko, but is indefinitely abandoned by him when he moves into another dimension with The Prophets. She then donned a nurse's uniform for a season (1998-1999) as Lynette Evans at ER's Chicago County General Hospital, alongside co-stars George Clooney, Anthony Edwards, and others, and keyed up for her most prominent role: Sherry Palmer, the wife of Senator David Palmer, and essentially a shrewd, diabolical, Lady Macbeth-like character willing to break any and every moral precept to lock down the presidency of her husband. More recently, Johnson portrayed Secretary of State Condoleeza Rice in the 2003 TV movie DC 9/11: Time of Crisis and again in another TV movie, The Path to 9/11, in 2006. Johnson married her husband, musician Gralin Jerald, in 1982. They have one daughter. In her off time, Johnson is actively involved with her church and with many progressive social causes; she played a significant role in securing aid for victims of Hurricane Katrina.

Trivia: A theater star from a diverse background, Ruben Santiago-Hudson was born in Lackawanna, NY, in 1956. Growing up with a combination of Puerto Rican and African American descent yielded many life-shaping experiences for Santiago-Hudson, and after studying at Binghamton University, he went on to write, direct, and star in the acclaimed play Lackawanna Blues, in which he portrayed over 20 characters from his past. The thespian would continue to work on-stage, appearing in plays like Jelly's Last Jam and Seven Guitars -- for which he won a Tony -- and additionally transitioned to the screen, appearing in a large number of films like The Devil's Advocate and Honeydripper. In 2005, Santiago-Hudson adapted Lackawanna Blues into a miniseries produced by HBO, which met with critical acclaim and garnered several major awards for star S. Epatha Merkerson. In the following years, Santiago-Hudson would find success on the popular series Castle.

Trivia: The slightly gritty and wizened Cuban-American actor Tony Plana boasts a resumé that is no less than extraordinary. Whatever the limitations of Hispanic typecasting, Plana soared high above them from the time of his debut in the early '80s, seeking out roles in several of Hollywood's most respected and venerable films -- ethnically themed and otherwise. He first culled attention as Rudy in Luis Valdez's stylized, theatrical period piece Zoot Suit (1981), starring a then-unknown Edward James Olmos. Plana's subsequent efforts read like a best-of early-'80s cinema; he tackled An Officer and a Gentleman (1982), Love and Money (1982), Valley Girl (1983), and El Norte (1983), all within a few years of one another. Plana was particularly effective as Fr. Manuel Morantes in John Duigan's wondrous, overlooked biopic Romero (1989, about archbishop and activist Oscar Romero) and as Carlos Bringuier in Oliver Stone's JFK (1991). In the 2000s, Plana unveiled a heightened interest in television, gracing the casts of such series as Ally McBeal and The Drew Carey Show as an occasional guest performer. Plana is best known to younger viewers, however, for two small-screen portrayals: that of cutthroat terrorist Omar in 24, and -- on a very different note, Ignacio -- the widower dad of the title character -- on the comedy drama Ugly Betty. Educationally, Plana trained in the drama programs at Loyola Marymount University and London's Royal Academy of Dramatic Art. He made the leap from acting to directing with two projects: A Million to Juan (1994, co-helmed with Paul Rodriguez) and The Princess and the Barrio Boy (2000). The latter constitutes Plana's directorial debut. It tells of a young well-to-do Hispanic woman (Marisol Nichols) who bucks convention by falling for a working-class boy, and simultaneously attempts to stand in the way of her father's marriage to a wicked lover.

Trivia: Blond-haired actor Blake Shields began his career with bit roles in such popular television series as Silk Stalkings, The West Wing, and Boy Meets World before transitioning into features in the independent film Crime and Punishment in Suburbia, with a more substantial role opposite Freddie Prinze Jr. marking his first leading role in a wide-release feature. Born in Ithaca, NY, Shields traveled the globe with his family as a youngster before they decided to settle in Israel for a five-year stretch. Upon returning stateside, Shields' family moved to Boise, ID, and the aspiring young actor ingratiated himself with the Idaho Shakespeare Festival and the Washington Street Players. A stint at the American Academy of Arts in Los Angeles found Shields starring in productions of A Midsummer Night's Dream, Burn This, and Hamlet among others, with performances as a street singer in Old Town Pasadena and Venice Beach helping the up-and-comer to better develop his vocal skills.After rebelling against the high-school administration in New Port South and joining the Judd Apatow crew in episodes of Freaks and Geeks and Undeclared, Shields found regular roles in HBO's Carnivàle and Showtime's Sleeper Cell, showing marked maturity while helping to solidify the foundation of an enduring career. He would go onto play a prominant role on the hugely successful series Heroes.
