Trivia: Tina Yothers rose to child stardom as Jennifer, the second-oldest child of the Keaton family, on Gary David Goldberg's quintessential '80s sitcom Family Ties (opposite Michael J. Fox, Meredith Baxter-Birney, and others). An actress from age three, born into a showbusiness family, Yothers signed one of her first major parts in 1981, shortly before the seven-year Family Ties assignment, when Alan Parker and co. tapped her to play the daughter of Albert Finney and Diane Keaton in his gut-wrenching treatment of a contemporary divorce, Shoot the Moon (1982). Yothers' post-Ties career placed its strongest emphasis on telemovies, such as Laker Girls (1990) and A Perry Mason Mystery: The Case of the Jealous Jokester (1995), and she achieved a colorful bit of recognition by playing scandal queen Tonya Harding in the TV movie Spunk: The Tonya Harding Story (1993). Though she would make a smattering of guest appearances on various TV shows, she didn't return to the screen in any regular capacity until she signed on for the fourth season of Celebrity Fit Club.

Trivia: Lead actor, onscreen from the '80s.

Trivia: Hardcore fans of the series Buffy the Vampire Slayer know actor Ken Lerner as Principal Flutie from the first few episodes of the series, but the Brooklyn native has appeared in a multitude of projects over the course of his career.

Trivia: Wil Wheaton was eight years old when he got his first showbiz break, appearing with Bill Cosby in a Jell-O pudding commercial. The following year (1982), Wheaton was prominently featured in the voiceover cast of the animated The Secret of NIMH. During this same period, he made his Los Angeles stage debut in a Company of Angels Theatre production of All My Sons. His starmaking turn was as Gordie Lachance, the Stephen King alter-ego, in the 1986 feature Stand By Me (1986). He then went on to play the title role in the 1987 Disney TV-movie Young Harry Houdini. Wheaton gained worldwide fame (and a worldwide website) as ensign Wesley Crusher in the weekly TV series Star Trek: The Next Generation, a role he played from 1987 to 1990. After leaving STNG on his own accord, Wheaton transitioned into adult roles with appearances in Flubber and a slew of independent films, and in 2001 he launched Wil Wheaton Dot Net, a blog that quickly gained a considerable following while turning the veteran actor into something of a geek icon. Meanwhile, in addition to staying busy with voice roles in such popular videogames as the Grand Theft Auto series and Fallout: New Vegas, Wheaton also contributed vocally to such animated television series' as Naruto, Ben 10: Alien Force, and Batman: The Brave and the Bold. In 2009 he began riffing on his own public persona with a recurring role as a fictional version of himself on The Big Bang Theory, and in 2010 he joined the cast of the quirky Sci-fi Channel series Eureka as Dr. Isaac Parrish. The author of both Dancing Barefoot and Just a Geek, Wheaton is the brother of actress Amy Wheaton.
