Peter Sellers plays Aldo Vanucci, aka the Fox (a master of disguise who cannot seem to stay out of jail), in this comedy directed by Vittorio De Sica and adapted from Somerset Maughan's novel by Neil Simon. Vanucci has come up with a new money-making scheme that involves moving gold bullion from Cairo to Rome. To cover his tracks, Vanucci poses as the director of a film about a robbery, which stars his talentless sister (Britt Ekland - and Mrs Sellers at the time) and a vain, has-been Hollywood star (Victor Mature in one of his funniest roles). He even manages to enrol almost the entire population of an Italian village as extras. However, someone smells a rat (or could it be a fox?).
