How to Steal a Million (1966)

When her art-forger father (Hugh Griffith) lends a fake statue to a museum exhibition, his straightlaced daughter (Audrey Hepburn) enlists an art thief (Peter O’Toole) to steal it back before the deception is found out. Though engaged to a wealthy American (Eli Wallach), she soon falls for her co-conspirator, who turns out to be an investigator in disguise. Director William Wyler shot this romantic caper on location in Paris, with Hepburn given a mod makeover and gowned in iconic Givenchy.
