Superman battles the Russians and the threat of nuclear holocaust in this cold-war inspired film. In addition, Lex Luthor cooks up a scheme to finish Superman once and for all… the creation of Nuclear Man, an evil being spawned from Superman’s own genetic material. Christopher Reeve’s final film appearance as Superman. This was a box-office and critical bomb and was panned by many. It would be almost 20 years until another Superman movie would be made.
