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: Made acting debut at age 7 as the evil character Ralph Rotten in a school play called Westward Ho Ho Ho. Participated in gymnastics and dance while in high school. Struggled with anorexia in the '90s. Based her role of Amber from Clueless on girls that she didn't like in high school. Joined the cast of Sabrina, the Teenage Witch during the show's fifth season as Morgan.

Trivia: Was cast as the lead in Guys and Dolls during his senior year of high school. Played Junior Varsity baseball while attending Harvard. Graduated college cum laude. Has a red belt in Tai Kwon Do. Worked as a substitute teacher after college.

Trivia: Willowy brunette actress Kate Jackson spent her early adulthood in summer stock, in training at the American Academy of Dramatic Arts, and as a page and tour guide at the NBC studios in Rockefeller Center. Anxious to burst forth with reams of dialogue as a film and TV actress, Jackson found herself in the utterly non-speaking role of a glamorous ghost on the mid-1960s daytime TV serial Dark Shadows. She was allowed to flap her gums a little more often as Jill Danko on TV's The Rookies (1973-76). Full stardom arrived for Jackson when she was cast as Sabrina Duncan, "the smart one" on the prime time jigglefest Charlie's Angels; she remained with this series from 1976 through 1979. Her last regular weekly TV effort was Scarecrow and Mrs. King (1983-1987) in which she played an average housewife who moonlighted as a secret agent. Though Jackson has made sporadic film appearances, it is safe to say that her greater fame rests upon her small-screen work. Jackson received an outpouring of industry sympathy and support when she battled breast cancer in the early 1990s. Kate Jackson has been a prolific and popular TV commercial spokesperson, and narrated Trouble in Mind, a series documenting the effects of mental illness, from 1999 to 2000.
