Superman IV: The Quest for Peace

“Nuclear Power. In the best hands, it is dangerous. In the hands of Lex Luthor, it is pure evil. This is Superman's greatest battle. And it is for all of us.”

A new figure is taking shape from a single strand of Superman's hair, and its maker is Lex Luthor (Gene Hackman), freshly out of jail. Sidney J. Furie sets him against Clark Kent (Christopher Reeve), who is trying to talk the world's governments out of their nuclear arsenals. Between them stands Lois Lane (Margot Kidder), who still has to decide how much of Clark she can keep apart from the hero.
