"Superman IV: The Quest for Peace" is a 1987 superhero film directed by Sidney J. Furie and starring Christopher Reeve as Superman. It is the fourth and final film in the original Superman film series, and follows Superman as he attempts to rid the world of nuclear weapons and prevent a global catastrophe. The film also stars Gene Hackman as Lex Luthor, Margot Kidder as Lois Lane, and Jon Cryer as Lenny Luthor.

The film received overwhelmingly negative reviews from critics and audiences alike, who criticized the film's poor special effects, weak script, and lack of originality. It was also a box office failure, grossing only $15.6 million against a budget of $17 million. The negative reception of "Superman IV: The Quest for Peace" effectively ended the original Superman film series, and the character would not appear in another live-action film until "Superman Returns" in 2006.

Despite its poor reception, "Superman IV: The Quest for Peace" has since gained a cult following among fans of the character and the film series. Some have praised its message of peace and nuclear disarmament, while others appreciate its campy, B-movie charm. However, the film is still generally regarded as a low point in the Superman film franchise and a cautionary tale for filmmakers looking to adapt comic book characters to the big screen.
