Trivia: The son of actor Lloyd Bridges, Beau Bridges (born Lloyd Vernet Bridges III) was actually named for his father; the nickname "Beau" was borrowed from Ashley Wilkes' son in Gone With the Wind. Beau received good billing for his secondary juvenile role in The Red Pony in 1949, although he was primarily seen in bit parts during the late '40s. This suited him fine; not all that interested in films, young Bridges had aspirations of being a basketball star. Despite being only 5'9", he played on the U.C.L.A. basketball team and at the University of Hawaii. But realizing that his height would always hold him back in professional sports, Bridges returned to acting via a small role on his father's TV series Sea Hunt. He made his stage debut in 1966's Where's Daddy and continued appearing in leading film roles throughout the 1960s and '70s, easing into character leads. Bridges directed two feature films, The Wild Pair (1987) and Seven Hours to Judgment (1988), in addition to the TV special The Thanksgiving Promise, in which virtually the entire Bridges clan (including his mother Dorothy) was cast. Bridges received Emmy and the Golden Globe awards for his portrayal of the title character in the 1992 TV movie Without Warning: The James Brady Story (1991), and won awards for his participation in the gloriously-titled made-for-cable The Positively True Adventures of the Alleged Texas Cheerleader-Murdering Mom (1993). He would continue to appear prominently both on the big and small screens over the coming decades, on shows like The Agency and Stargate: Atlantis and in films like The Good German and The Ballad of Jack and Rose.

Trivia: The son of an editor for the New Yorker, the diminutive comedic actor Wallace Shawn achieved immortality for his portrayal of the Sicilian Vizzini in the 1987 classic The Princess Bride. A graduate of both Harvard and Oxford University, he has taught several courses in English and struggled as a playwright in the early '70s; in 1977 he translated Machiavelli's The Mandrake. Shawn broke into films soon after, building a successful career as a supporting actor to help fund his playwriting. He debuted in two of the best films of 1979: Woody Allen's Manhattan and Bob Fosse's All That Jazz.In 1981, he co-wrote the semi-autobiographical My Dinner With André, a talky comedy starring himself and theater director André Gregory in a dinner conversation, directed by Louis Malle. The movie was acclaimed by critics and a cult favorite. After this personal project, Shawn would build a career out of playing brief but surprisingly memorable roles in a long list of movies. His performance as the leader of the misfit criminal gang in The Princess Bride proved a pivotal moment, and that same year, he supplied the heroic voice for the Masked Avenger in Woody Allen's Radio Days. Shawn would also go on to do voice acting in projects like The Goofy Movie, All Dogs Go to Heaven, and the Toy Story series. He would also continue to work with Woody Allen throughout the next decade, and picked up a new generation of fans playing debate teacher Mr. Hall in the 1995 high school classic Clueless. Shawn would also take his quirky persona to the small screen with appearances on TV shows likeMurphy Brown, The Cosby Show, Star Trek: Deep Space Nine, Sex and the City, as well as the ABC sitcom version of Clueless. Throughout his acting career, Shawn has managed to continue writing successful plays, and eventually adapted one of them, The Designated Mourner, for a feature film in 1997. In 2002, he played the publishing boss Mr. Gelb for the "Greta" story in Rebecca Miller's Personal Velocity: Three Portraits. Shawn would continue to appear regularly on screen in the years to come, playing recurring roles on The L Word, Gossip Girl, and Eureka,
