Paul Verhoeven's American breakthrough film, RoboCop, is an exceedingly violent blend of black comedy, science fiction, and crime thriller. Set in Detroit sometime in the near future, the film is about a policeman (Peter Weller) killed in the line of duty whom the department decides to resurrect as a half-human, half-robot supercop. The RoboCop is indestructible, and within a matter of weeks he has removed crime from the streets of Detroit. However, his human side is tortured by his past, and he wants revenge on the thugs who killed him. The film was later followed by two feature-length sequels and a live-action television series, neither of which were as successful as the original film.
