American actor Grant Williams is best remembered for playing the lead in the memorable sci-fi film The Incredible Shrinking Man. Before breaking into films in 1956 in Red Sundown, Williams had attended three colleges and spent four years in the U.S. Air Force. He then trained under Lee Strasberg and performed in summer theater. He also appeared occasionally on television. Following his success with The Incredible Shrinking Man, Williams continued making film and television appearances, but none of them attracted much notice. Eventually he launched his own acting school. Williams also wrote text books on acting.
