Trivia: After spending the 1990s as a TV teen star, Melissa Joan Hart set her sights on feature films. Born and raised on Long Island, Hart began acting in TV commercials as a child. She further honed her skills in New York theater in the late '80s as the youngest member of the Circle Repertory Lab Company. Hart then broke through as a cable TV favorite (and a CableACE Award nominee) in the role of the precocious titular preteen on the Nickelodeon series Clarissa Explains It All (1991-1994). After the series ended, Hart moved to network TV stardom in 1996 as the supernaturally gifted title teen on Sabrina, the Teenage Witch. Maintaining her pert primetime persona while revealing her range, Hart also starred in several TV movies, including Family Reunion: A Relative Nightmare (1995), Twisted Desire (1996), The Right Connections (1997), and the college date rape drama Silencing Mary (1998). Though Hart continued to produce and star in Sabrina, she also attempted to parlay her TV fame into movie stardom with the romantic comedy Drive Me Crazy (1999). The film, however, failed to perform as well as the Britney Spears tune that gave it its title. Hart raised eyebrows that same year when she tried to shed her squeaky-clean adolescent image with a racy photo spread and interview in men's magazine Maxim. Neither gambit affected Sabrina, although Hart and the series moved from the family-oriented ABC lineup to the youth-savvy WB in 2000. She lent her vocal talents to the Batman Beyond series, and continued to work steadily in made-for-TV fare like Rent Control, Holiday in Handcuffs, and My Fake Fiance. In 2010 she teamed up with fellow former child star Joey Lawrence for TV series Melissa & Joey that ran on the ABC Family channel.

Trivia: Known to millions as the adorable Punky Brewster, actress Soleil Moon Frye began acting when she was only two years old. The daughter of actor Virgil Frye, Soleil cut her teeth on projects like the TV movie Who Will Love My Children? before scoring the role of Punky at the age of eight. Audiences fell in love with the precocious child, and she stayed with the show until 1988. After it wrapped, Frye continued to remain creative and active, appearing in three seasons of Sabrina, the Teenage Witch, doing voiceover work for shows like The Proud Family and Planet Sheen, working in films such as Summertime Switch and even directing the 2004 film Sonny Boy.

Trivia: As Mini-Me in Austin Powers 2: The Spy Who Shagged Me (1999), Verne Troyer earned his claim to fame as the smaller imitation sidekick of Dr. Evil (Mike Myers). The hilarious summer sequel to Austin Powers received critical acclaim, as well as success at the box office, in addition to sending Troyer into stardom.Born January 1, 1969, in Sturgis, MI, Troyer began his acting career in 1993, after relocating to Arlington, TX. Standing less than three feet tall, he appeared in his first feature role in Baby's Day Out, playing the stunt double of the film's nine-month-old protagonist. He then appeared in numerous films including My Giant (1998) and Wes Craven's Wishmaster (1997), as well as the 1997 alien movie Men in Black starring Will Smith.After standing in the limelight of Austin Powers 2 in 1999, Troyer found roles in several major motion pictures. In The Grinch -- the Christmas 2000 Dr. Seuss-based feature starring Jim Carrey -- Troyer played a dual role as two different "Who's" (elf-like inhabitants of "Whoville"). He appeared in the strange -- even distasteful -- romantic comedy Bubble Boy in 2001, as Dr. Phreak. That same year, the box-office smash hit Harry Potter and the Sorcerer's Stone incorporated a ghoulish Troyer. Returning to the role that catipulted him to stardom in 2002's Austin Powers in Goldmember found Troyer taking on his most substantial role to date, with many of the film's key scenes featuring Troyer at his comic best. He joined the cast of the reality program The Surreal Life in 2005, and two years later appeared in the infamous video-game adaptation Postal. He had a major role as a hockey coach in Mike Meyer's 2008 comedy The Love Guru, and he was cast by Terry Gilliam in The Imaginarium of Doctor Parnassus.
