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: Yale alumnus Robert Picardo made his off-Broadway debut in David Mamet's one-act play Sexual Perversity in Chicago. That was in 1975; two years later, Picardo was first seen on Broadway in Gemini. He launched his TV career in the 1980 miniseries The Dream Merchants, and in 1981 made his first film, The Howling--one of several assignments for director Joe Dante. During his early TV years, he was all too often cast in "first husband" or "wrong boyfriend" supporting roles. Things improved in 1986, when he was hired to play the much-feared high school gym teacher Coach Cutlip in the weekly dramedy The Wonder Years. He went on to co-star as Dr. Dick Richard in the highly acclaimed Vietnam-era series China Beach (1989-91). A busy voiceover artist, Picardo has supplied a variety of vocal characterizations for such series as Dinosaurs and Batman. Undoubtedly you'll be reading even more about Robert Picardo in the future, by virtue of his being cast as the holographic Doc Zimmerman on TV's Star Trek: Voyager(1995- ). In the post Star Trek years, Picardo would find ongoing success on shows like The Lyon's Den, Stargate SG-1, and Stargate Atlantis.
