Steel is a 1997 American superhero film loosely based on the DC Comics character of the same name. The film stars Shaquille O'Neal as John Henry Irons and his alter-ego Steel, Annabeth Gish as his wheelchair-using partner Susan Sparks, and Judd Nelson as their rival Nathaniel Burke. The plot centers on an accident caused by Burke which leaves Sparks paralyzed. The accident results in Irons quitting his job. Burke begins mass-producing weapons and selling them to criminals. In order to stop Burke, Irons and Sparks create a suit of armor that leads Irons to become the superhero Steel.

Written and directed by Kenneth Johnson, the film separates itself from the comic book series (and John Henry Irons' status as a supporting character of Superman) by using original protagonists and antagonists. Upon its initial release, Steel was a box-office bomb and was panned by critics, who complained about the film's "cheesiness" and poor acting.
