Golden Globe-nominee Christopher Reeve reprises his popular title role in the fourth and final installment in one of the all-time most successful motion picture series ever (earning $320,000,000 combined). Here the Man of Steel is faced with his most important and toughest mission ever -- to rid the world of all nuclear armaments. But first he must win his battle against Lex Luther's new creation whose powers equal, if not surpass, those of Superman. This installment reunites Oscar-winner Gene Hackman ("Unforgiven," "The Firm"), Margot Kidder, Jackie Cooper and Marc McClure and co-stars Mariel Hemingway ("Civil Wars," "Star 80") and Jon Cryer ("Pretty in Pink").
