Superman IV: The Quest for Peace (1987) and the Comics

https://www.batman-online.com/forum/index.php?topic=2270.0

Superman IV was produced at the height of the Cold War and reflects the fears many people had at the time regarding the threat of nuclear war. The central plot sees the Man of Steel vowing to rid the Earth of all nuclear weapons in the hopes of preventing such a conflict from occurring. The film's central themes are similar to those explored in 'The Day the Earth Died!' (Superman #408, June 1985).
