Mr. Peek-a-Boo (original French title: Garou-Garou, le passe-muraille, often shortened to Le Passe-muraille) is a 1951 French fantasy comedy film directed by Jean Boyer, which premiered on 6 April 1951. It is adapted from Marcel Aymé's 1941 short story about an ordinary man who discovers that he can walk through walls. The screenplay was written by Michel Audiard and Jean Boyer.
