Blue Steel is a 1990 American action thriller film directed by Kathryn Bigelow and starring Jamie Lee Curtis, Ron Silver and Clancy Brown. The film is about a New York police officer who shoots and kills an armed criminal on her first day of active duty, only for a witness of the incident to steal the criminal's weapon and begin tormenting her life as the object of a homicidal obsession.

Blue Steel was originally set to be released by Vestron Pictures and its offshoot label Lightning Pictures, but the film was ultimately acquired by Metro-Goldwyn-Mayer due to Vestron's financial problems and eventual bankruptcy. The film was green lit and produced by Lawrence Kasanoff, Lightning’s head of production at that time.
