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: Born in 1977, actress Lindsay Sloane enjoyed a series of assignments during her adolescent years, including a stint on The Wonder Years (as Alice Pedermeir, the girlfriend of high schooler Chuck Coleman) and another on Sabrina the Teenage Witch. In her early years, she found herself somewhat typecast in playing the quirky best friends of female lead characters, but shortly after her 20th birthday, she aggressively changed her image (by virtue of rhinoplasty) and scored a key role as a cheerleader, Big Red, in the farcical sports comedy Bring It On (2000). Following enlistment in a couple of very short-lived television series (the 2000 Grosse Pointe and the 2001 Going to California), and an assignment as Albert Brooks' daughter in the comedy remake The In-Laws (2003), Sloane chalked up a series of parts in big-screen outings, including In The Land of Women (2007), The Accidental Husband (2007), and Over Her Dead Body (2008).

Trivia: Emile Hirsch rose to prominence in 2002 with showy roles in two high-profile films: The Dangerous Lives of Altar Boys and The Emperor's Club. Hirsch was born in Topanga Canyon, CA, on March 13, 1985. He made his television debut at the age of 11 in an episode of the series Kindred: The Embraced. After a number of small guest roles on Two of a Kind, Sabrina, the Teenage Witch and Third Rock From the Sun, Hirsch moved on to more dramatic roles with appearances of NYPD Blue and ER. He appeared in a pair of made-for-TV movies, Gargantua and Houdini (in the latter playing the famed magician Harry Houdini as a boy) before making his big-screen debut as pensive Catholic school student Francis in The Dangerous Lives of Altar Boys, which earned the teenager a number of enthusiastic reviews. After appearing in the made-for-cable drama Wild Iris, Hirsch appeared as a bright but rebellious student in the Kevin Kline vehicle The Emperor's Club. Hirsch was praised for his roles in Imaginary Heroes (2004) and Lords of Dogtown (2005), though the films themselves received lukewarm reviews. His luck would change when he was cast as a young man who finds himself while hitchhiking America for 2007's Into the Wild. Based on the popular novel from Jon Krakauer, Sean Penn directed the film, which would earn Hirsch a Best Actor nom from the Broadcast Film Critics Association. Hirsch reunited with Penn to play a young gay rights activist in Milk, the multi-Academy Award winning biopic of politician and activist Harvey Milk. He lent his voice for X Games 3D: The Movie in 2009, and starred in Taking Woodstock (2009), a biopic chronicling a face-off between the owners of a small motel, and the organizers of the original Woodstock. He took a supporting role in Oliver Stone's 2012 film The Savages.

Trivia: Child actor Frankie Muniz shot to stardom as the titular genius mired in a family of underachievers in Fox's single-camera smash sitcom Malcolm in the Middle. Able to mix his apple-cheeked features with intelligent acting, Muniz quickly became a darling to some critics. Other critics predicted he would become the Fred Savage of his generation, meaning he would fail to carry his childhood television success into an adult career. Francisco James Muniz IV was born on December 5, 1985, in Ridgewood, NJ. Raised in Knightdale, NC, Muniz found his interest in acting ignited by watching his older sister in a play. He was soon cast as Tiny Tim in a local production of A Christmas Carol, a role he reprised the next two seasons. Productions of The Sound of Music, The Wizard of Oz, and Our Town fleshed out his regional theater resumé. Muniz made his television debut in the made-for-TV movie To Dance With Olivia (1997), starring Lou Gossett Jr. He next appeared in the CBS Hallmark Hall of Fame presentation of What the Deaf Man Heard (1997). A small role in Lost & Found (1999) led up to the breakthrough that would make him a familiar face in millions of households. Fox premiered Malcolm in the Middle as a mid-season replacement in 2000, and the show was quickly swamped with accolades. Matriarch Jane Kaczmarek may have received the lion's share, but it was Muniz's job to anchor the show with his narration and his central role in many of the dysfunctional, envelope-pushing plots. He was twice nominated for Golden Globes in 2000 and 2001, and was honored with the Hollywood Reporter Young Star Award for his work in the series. Muniz's first starring role on the big screen was as Willie Morris in the family period piece My Dog Skip (2000), released right around the time of the Malcolm pilot. Muniz then contributed a voice to the animal cast of Dr. Dolittle 2 (2001). He had a moderate-sized hit with the 2002 release Big Fat Liar, which teamed him with Amanda Bynes as a pair of students seeking revenge on a sleazy movie producer (Paul Giamatti) who steals their idea. He was also part of the ensemble for the 2002 gang film Deuces Wild.
