Superman III is a 1983 superhero film directed by Richard Lester from a screenplay by David Newman and Leslie Newman based on the DC Comics character Superman. It is the third installment in the Superman film series and a sequel to Superman II (1980). The film features a cast of Christopher Reeve, Richard Pryor, Jackie Cooper, Marc McClure, Annette O'Toole, Annie Ross, Pamela Stephenson, Robert Vaughn, and Margot Kidder.Although the film recouped its budget of $39 million, it proved less successful than the first two Superman films, both financially and critically. While harsh criticism focused on the film's comedic and campy tone, as well as on the casting and performance of Pryor, the special effects and Christopher Reeve's performance as Superman were praised.

A sequel, Superman IV: The Quest for Peace, was released in July 1987.
