Charade is a 1963 Technicolor American romantic comedy/mystery film directed by Stanley Donen, written by Peter Stone and Marc Behm, and starring Cary Grant and Audrey Hepburn. The cast also features Walter Matthau, James Coburn, George Kennedy, Dominique Minot, Ned Glass, and Jacques Marin. It spans three genres: suspense thriller, romance and comedy. Because Universal Pictures published the movie with an invalid copyright notice, the film entered the public domain in the United States immediately upon its release. The film is notable for its screenplay, especially the repartee between Grant and Hepburn, for having been filmed on location in Paris, for Henry Mancini's score and theme song, and for the animated titles by Maurice Binder. Charade has received generally positive reviews from critics, and was additionally noted to contain influences of genres such as whodunit, screwball and spy thriller; it has also been referred to as "the best Hitchcock movie that Hitchcock never made."
