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: Martin Mull intended to become a painter when he enrolled in the Rhode Island School of Design, but his Scaramouche-like sense of the ridiculous led to a career as a nightclub comedian. The deceptively conservative-looking Mull is widely recognized as one of the most accomplished satirists in show business. Even before he gained TV fame, Mull's barbed comedy albums had earned him a following on the college campus circuit. His first major TV assignment was Mary Hartman Mary Hartman (1976-77), where he was seen as Garth Gimble, an ill-tempered wife beater who ended up being impaled by a Christmas tree. When Mary Hartman Mary Hartman producer Norman Lear developed the spin-off series Fernwood Tonight in 1977, Mull was brought back as glad-handing emcee Barth Gimble, Garth's twin brother. In films since 1978, Mull is often called upon to portray an underhanded or vacillating CEO (vide Mister Mom). His well-groomed mustache and tweedy appearance served him well as Colonel Mustard in the 1985 movie version of the venerable board game Clue. Back on television, Mull has etched such indelible comic characterizations as Leon Carp, Roseanne Connor's gay boss, on Roseanne (1988- ), and the leading roles of Martin Crane in Domestic Life (1984) and Dr. Doug Lambert in His & Hers (1990). In collaboration with Allan Rucker, Martin Mull was the creator/writer of a devastating series of lampoonish "cultural studies" books and TV specials, under the blanket title The History of White People in America.

Trivia: Born in Montreal, Quebec, Caroline Rhea launched herself on the path to stardom in 1986, when the then-22-year-old moved to Manhattan and enrolled in the New School for Social Research's standup comedy program. On the side, Rhea cut her chops by practicing at the standup club Catch a Rising Star, and the success of those engagements yielded additional bookings, not simply at Big Apple venues, but on such national television programs as Comic Strip Live and Caroline's Comedy Hour. Rhea segued into scripted television programs and features around 1996, with roles on such sitcoms as Sabrina the Teenage Witch and The Drew Carey Show, before hitting a watershed moment in her career: the launch of her own eponymous series, the talk program The Caroline Rhea Show (which followed her guest-hosting of The Rosie O'Donnell Show). Unfortunately, Rhea's talk show folded less than a year after its 2002 premiere, but Rhea continued to build her own reputation, with popular standup bookings across the U.S. and Canada, appearances on talk programs such as Live with Regis and Kelly, and small roles in movies. She played Candi in the disastrous Tim Allen holiday comedy Christmas With the Kranks (2004) and Gloria in the Mark Rosman-directed teen movie The Perfect Man (2005), and hosted the popular series The Biggest Loser, a reality series in which contestants compete to determine who can lose the most weight. In 2006, Rhea also hosted the made-for-cable standup special Caroline Rhea: Rhea's Anatomy, which found her offering witty divertissements on such subjects as post-40 pregnancy and age-disparity romances.

Trivia: American comic actor Henry Gibson acted professionally since childhood, but didn't gain prominence until his discovery by Jerry Lewis for a role in The Nutty Professor (1963). Gibson quickly developed a comedy act for TV variety shows, in which he passed himself off as a fey, Southern-accented "blank verse" poet. So convincing was this persona that many viewers believed Gibson was a genuine Southerner, though he actually hailed from Pennsylvania. He played a cruder variation of his yokel character as a patron of the "Belly Button" bar in Billy Wilder's Kiss Me Stupid (1964), and was hilarious as a hip-talking Indian in the Three Stooges' feature film The Outlaws is Coming (1965). Gibson might have continued in small roles indefinitely had he not been catapulted to stardom in 1968 as part of the ensemble on TV's Rowan and Martin's Laugh-In, where his introductory "A poem...by Henry Gibson" became a national catchphrase. Gibson stayed with Laugh-In until 1971, whereupon he launched a reasonably successful career as a straight character actor. One of his best film roles of the '70s was Haven Hamilton, a hard-driving, flag-waving country-western star in Nashville (1975). Gibson not only delivered an expert performance but also co-wrote the songs sung by Haven Hamilton, including the deliberately banal Bicentennial ballad, "200 Years", in one of the film's early scenes. Henry Gibson continued throughout the next two decades playing strong movie character parts (the neo-Nazi commander in 1980's The Blues Brothers) and bright little cameos (the closet-smoking security guard in 1990's Gremlins 2). Gibson was also ubiquitously available as a guest star on such cable-TV reruns as Bewitched (he played a leprechaun) and F Troop (he was jinxed Private Wrongo Starr). He died of cancer in September 2009, about a week before his 74th birthday.
