The film challenges conventions of film noir by not including a femme fatale and making one of the police officers the killer instead of a psychotic criminal. It incorporates aspects of film noir like two differing authoritative figures, black and white scenes, and dark shadows. The film also includes mystery through a flashback scene and crime through a final murder scene. It draws inspiration from Frank Miller's Sin City and The Usual Suspects by using title sequences between action scenes rather than at the beginning or end.
