Born in Pasadena, California, George Nader became interested in acting while still in school and appeared in several productions at the Pasadena Playhouse. This led to several small parts in movies before earning the lead role in the infamous 3D thriller Robot Monster (1953). The movie was bad but profitable, and Nader soon had a contract with Universal Pictures. Unfortunately, the studio already had on its roster such good-looking and athletic actors as Rock Hudson, Tony Curtis and Jeff Chandler, so Nader often found himself being cast in their leftovers, usually playing parts that emphasized his "beefcake" appeal. (At 6' 1" and 180 pounds, Nader had the kind of physique fan magazines drooled over and unlike many of his colleagues, he frequently appeared with his chest hair intact.) However, he did enjoy a few good years in the mid-1950s, turning in a commendable performance in Brisants humains (1956) before his career began to decline. He tried his hand at three TV series and then relocated to Europe, where he enjoyed a modest revival in the late 1960s starring as "Jerry Cotton" in a series of West German films.
