Trivia: An unpredictable comic whose talents as an artist and writer of children's books frequently goes unnoticed in favor of such antics as appearing on the Late Show With David Letterman in peanut butter-covered boots, Harland Williams set the tone for his cinematic career as a urine-chugging state trooper in the Farrelly brothers' sophomoric smash Dumb and Dumber (1994).Born in Toronto, Ontario, the artistically inclined Williams aimed to refine his passion for drawing and painting at Canada's prestigious Sheridan College in Oakville, Ontario. Childlike curiosity combined with his love of art drove Williams to create a series of popular children's books in which a similarly curious young dinosaur named Lickety Split embarks on a series of amazing adventures and learns important life lessons in the process. Finding a creative outlet in poetry and painting while working as a forest ranger for five years after dropping out of Sheridan College, Williams set his goals to leave the forest as a standup comic and actor, soon moving to L.A. to pursue his newfound calling.After his memorable debut in Dumb and Dumber, Williams appeared briefly in the television series Simon before attempting a starring vehicle with Disney's Rocketman in 1997. Trashed by critics and largely ignored by audiences, Rocketman may not have launched Williams' career into the stratosphere, but it did result in a number of memorably comedic roles in such popular comedies as Half-Baked (1998) and There's Something About Mary (1998). The new millennium also proved to be a busy year for Williams in both his career as a standup and an actor: serving as host of Comedy Central's Premium Blend, appearing in the Geena Davis Show, The Whole Nine Yards, and as an abrasive tyrant television star who learns the true value of love in Becoming Dick. In 2001, Williams appeared as the compound-fractured friend of a spastic Tom Green in Freddy Got Fingered. The following year found Williams as a gender-bending college student alongside co-stars Barry Watson and Michael Rosenbaum in Sorority Boys.

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: In feature films, actress Jennifer Elise Cox is best known for her funny, fractured performance as perennially slighted middle child Jan Brady in The Brady Bunch Movie and A Very Brady Sequel. Before making her film debut in the former, Cox had experience on stage, including appearances in two operas in New York, Don Giovanni and Madame Butterfly, and has guest starred on television series, including Murphy Brown and Wings.

Trivia: New Jersey-born actor Josh Flitter became a familiar face to audiences at a young age when he started appearing in movies like Eternal Sunshine of the Spotless Mind and The Greatest Game Ever Played by the time he was ten. Flitter's mother had appeared in off-Broadway plays, but for the most part the young performer's home life was normal and suburban, and his interest in show business came from the talent he showcased in his first few endeavors. In 2007, casting directors caught onto Flitter's charm and cast him in not one but two prominent roles: the choir boy in License to Wed and Corky in Nancy Drew. The young man began appearing on late-night talk shows to promote his films, and began developing a substantial fan base -- and he hadn't even had his bar mitzvah yet.

Trivia: Encouraged by better-than-average success as a stage performer in such plays as Mister Roberts and The Seven Year Itch, American actor Rance Howard decided to try his luck in Hollywood. Talent, however, meant less than star appeal in Tinseltown, thus Howard was confined to small roles which took only minimal advantage of his abilities. Howard's wife Jean was also an actress, but retired to raise their son Ron (both mother and child appeared in the 1956 Western Frontier Woman). Ron was photogenic enough to attain supporting parts on various TV shows and films, leading to a regular role as Opie on The Andy Griffith Show (1960). Those cynics who believe that Rance Howard forced his son into acting in order to create a meal ticket are referred to a well-known anecdote concerning the earliest years of the Griffith program. Little Ron decided to test his value by throwing a temper tantrum -- whereupon Rance took the boy aside, gave him a spanking, and told his son that if he didn't want to act like a professional he'd have to go home and forget about acting. While Rance certainly did not rely on Ron's fame alone to get work (he remained a busy stage actor), it is true that Ron recommended his dad for supporting roles in such films as The Music Man (1962) and The Courtship of Eddie's Father (1963), both of which featured the younger Howard. When child star Ronny Howard became A-list film director Ron Howard in the '80s he continued casting both dad Rance and younger brother Clint Howard in Splash (1984) and other films. Rance Howard remained a reliable general purpose actor well into the 2000s.

Trivia: Actor Jake Johnson began his career in the virgin territory of the Internet, appearing in the popular Michael Cera web series Clark and Michael in 2006. He would go on to make appearances on Curb Your Enthusiasm and The Unit, as well as in the David Mamet film Redbelt, before collaborating with Cera once again for 2009's Paper Heart. He appeared in the comedy Get Him to the Greek, and had a very busy 2011 with parts in No Strings Attached, A Very Harold & Kumar Christmas, and a major part in the new FOX sitcom New Girl. He also appeared in the comic big-screen version of 21 Jump Street the next year.
