Directed by Vittorio De Sica, After the Fox is a crime comedy starring Peter Sellers as a flamboyant master thief who disguises a jewel heist as the production of a World War II film. As criminals pose as filmmakers on the Italian coast, deception and farce escalate through mistaken identities and cultural clashes. Written by Neil Simon, the film blends European comic tradition with American verbal humor and elaborate disguise-driven comedy.

One of the world's greatest criminals and conmen, Aldo 'The Fox' Vanucci (Peter Sellers) has finally struck gold but to traffic his embezzled bullion he must enact his most outrageous scheme yet disguised as a neo-realist film director.

Co-starring Victor Mature and Britt Ekland, and directed by Vittorio De Sica, After the Fox is a madcap comedy caper, at once both a zany heist farce and a riotous filmmaking satire.
