Opening sequence shows Superman has picked up the spirit of glasnost as he flies into space to rescue an imperiled cosmonaut and utters his first lines of the picture in Russian.
Superman’s newly assumed mission sees him addressing the United Nations to tell the world he personally is going to remove all nuclear weapons from the face of the earth.
Meanwhile, Lex Luthor (Gene Hackman) has created an evil clone of Superman called Nuclear Man, who wreaks havoc with famous landmarks around the world and does savage battle with the hero on the face of the moon until Superman discovers his nemesis’ single flaw.
The earlier films in the series were far from perfect, but at their best they had some flair and agreeable humor, qualities this one sorely lacks. Hackman gets a few laughs, but has less to work with than before, and everyone else seems to be just going through the motions and having less fun doing so.
