Here was a case in which the progenitors of this successful comic-book adaptation figured they had to go in a new direction--and chose the wrong one. For starters, they recruited comedian Richard Pryor, who was the kiss of death for almost every movie he was in except his own concert films. He plays a computer specialist who is hired by a criminal mastermind (Robert Vaughan) to help him take on Superman by exposing him to a new form of Kryptonite: red Kryptonite, which always had unpredictable effects in the comic books. In this film, it splits Superman in two, dividing his good self from his dark side. The special effects had gone about as far as they could, and this movie strains to hold an audience's interest for its full running length. --Marshall Fine
