Though he's had many noteworthy roles over the course of his long career, character actor Glenn Corbett will forever be remembered for his guest role on "Star Trek" as Zefram Cochrane, the inventor of warp drive. After serving a stint in the military, Corbett began acting in plays at the local college where his wife worked; he made his film debut in 1959 opposite James Shigeta in the Japanese-American crime thriller "The Crimson Kimono," and he soon transitioned to television. He next landed a starring role on the short-lived sitcom "It's a Man's World," about four college-age men living on a houseboat in Ohio, and scored critical and commercial success with his portrayal of recently returned Vietnam veteran Lincoln Case in the road trip serial "Route 66." His tenure on the show marked the first time a TV series had featured a notable character with first-hand experience in the war, and many of Case's storylines dealt with his struggle to reconcile his violent past with his uncertain future. After the series was canceled in 1964, Corbett was cast as James Stewart's headstrong son in the Oscar-winning western "Shenandoah," and later, he portrayed friendly buffalo hunter Pat Garrett in the John Wayne western drama "Chisum." After a decade of steady supporting roles, Corbett became a series regular on the prime-time soap opera "Dallas," playing defense lawyer Paul Morgan from 1983 to 1988.
