Nuclear Man

Superman IV: The Quest for Peace is a 1987 superhero film, the last of the Superman theatrical movies starring Christopher Reeve as the Man of Steel. In this film, Superman battles Lex Luthor (Gene Hackman) and his creation, a solar-powered evil clone of Superman called Nuclear Man.

Unlike the previous three movies, which were produced by Alexander and Ilya Salkind, the fourth movie was produced by Golan-Globus's Cannon Films, in association with Warner Bros. Superman IV was neither a critical nor a box office success, and the series went on hiatus until Superman Returns in 2006.

After saving a group of cosmonauts whose ship is jeopardized by a rogue satellite, Superman visits his hometown of Smallville disguised as Clark Kent, checking in on the uninhabited farm where he grew up. In an empty barn he uncovers the space-capsule he was sent to Earth in, and removes a green-glowing, Kryptonian energy module. A recording left by his birth mother, Lara, states that its power can only be used once.

Unwilling to sell the land to a mall developer, Superman returns to Metropolis and stops a runaway subway train. Returning to the Daily Planet as Clark Kent, he learns that the newspaper has been taken over by David Warfield, a tabloid tycoon who fires Perry White and hires his daughter Lacy (Mariel Hemingway) as the new editor. Lacy takes a liking to Clark and tries to seduce him. Clark agrees to go on a date with her.
