Trivia: A reclusive character actor with an elongated, skull-like face, manic eyes and flexible facial expressions, Christopher Lloyd is best known for portraying neurotic, psychotic, or eccentric characters. He worked in summer stock as a teenager, then moved to New York. After studying with Sanford Meisner at the Neighborhood Playhouse, he debuted on Broadway in Red, White and Maddox in 1969. Lloyd went on to much success on and off Broadway; for his work in the play Kaspar (1973) he won both the Obie Award and the Drama Desk Award. His screen debut came in the hugely successful One Flew Over the Cuckoo's Nest (1975), in which he played a mental patient. He went on to appear in a number of films, but first achieved national recognition for playing the eccentric, strung out, slightly crazy cab-driver "Reverend" Jim in the TV series Taxi from 1979-83; he won two Emmy Awards for his work. He extended his fame to international proportions by playing the well-meaning, wild-haired, mad scientist Doc Brown in Back to the Future (1985) and its two sequels; this very unusual character continued the trend in Lloyd's career of portraying off-the-wall nuts and misfits, a character type he took on in a number of other films in the '80s, including The Addams Family (1991), in which he played the crazed uncle Fester. His "straight" roles have been infrequent, but include Eight Men Out (1989).

Trivia: There's no mystery concerning the hometown of George Wendt. The heavyset, curly haired actor never misses a talk show opportunity to cheer on his beloved Chicago "Cubbies" or "Da Bears." After theater work in Chicago and New York and a handful of TV appearances on sitcoms like M*A*S*H and Alice, Wendt inaugurated his signature role of burly, unemployed barfly Norm Peterson on TV's long-running Cheers (1983-1993); so far as it can be determined, he still hasn't paid his bar tab, which according to TV Guide totalled up to 64,218 dollars at the end of 11 seasons. He starred in the short-lived The George Wendt Show, and continued to work steadily on both the small and big screen in a variety of projects including Spice World, Outside Providence, Teddy Bears' Picnic, and Edmond. He also reprised his iconic role of Norm on an episode of the successful Cheers spinoff Frasier.

Trivia: Somewhere between John Goodman and Robert Loggia -- at least on a physical scale -- there exists portly screen presence Paul Rae. A consistently reliable supporting player whose undeniable onscreen charisma has made him equally popular on film and television, Rae has appeared on the silver screen in such films as Coach Carter, Next, and Daddy Day Camp, and on the small screen in such shows as Desperate Housewives, The West Wing, and The Closer. Despite the fact that Rae has only been active in the entertainment industry since 2003, he has racked up an impressive list of credits while working with some of the biggest names in Hollywood, and proven himself equally adept at all genres.

Trivia: Zachary Gordon began his career at the tender age of nine, playing a bratty kid at a barbecue in the 2007 comedy Sex and Death 101. The California native subsequently wasted no time building up his momentum as an actor, amassing a résumé over the coming years that included roles in National Treasure: Book of Secrets, The Brothers Bloom, and Madagascar: Escape 2 Africa, as well as on shows like How I Met Your Mother, All of Us, and Ni Hao, Kai-Ian. In 2010, Gordon joined cast of the highly anticipated kids movie Diary of a Wimpy Kid, playing the leading role of Greg Heffley, before signing on to appear in Beverly Hills Chihuahua 2 later that year.
