Revolver is a 2005 action thriller film co-written and directed by Guy Ritchie, and starring Jason Statham, Ray Liotta, Vincent Pastore and André Benjamin. The film centres on a revenge-seeking confidence trickster whose weapon is a universal formula that guarantees victory to its user, when applied to any game or confidence trick.

This is the fourth feature film by Ritchie and his third to centre on crime and professional criminals, but also has a strong philosophy and Buddhist moral content. It was released in UK cinemas on 22 September 2005. It performed poorly at the box office and received negative reviews. A reworked version was released to a limited number of US theatres on 7 December 2007.
