Superman IV: The Quest for Peace

To make the world safe for nuclear arms merchants, Lex Luthor (Gene Hackman) creates a new being to challenge the Man of Steel: the radiation-charged Nuclear Man (Mark Pillow). The two foes clash in an explosive extravaganza that sees Superman save the Statue of Liberty, plug a volcanic eruption of Mount Etna and rebuild the demolished Great Wall of China.
