Trivia:
Some reference works state that "Adventures of Superman" (1952) star George Reeves appeared as a television news reporter with eyeglasses in one sequence. This is not true. The actor playing the role bears no resemblance to Reeves, and in a 1995 interview with Reeves biographer Jim Beaver, director Robert Wise stated unequivocally that it is not Reeves in the role.
