How to Steal a Million is a 1966 American heist comedy film directed by William Wyler and starring Audrey Hepburn, Peter O'Toole, Eli Wallach, Hugh Griffith, and Charles Boyer.

Late one night at their mansion, Nicole encounters a burglar, Simon Dermott, holding her father's forged "Van Gogh".

Wanting to avoid an investigation that would uncover her father's fake masterpieces, Nicole does not contact the police, and instead drives the charming Simon to his lavish hotel in his expensive sports car.

After observing the guards' routine, Simon repeatedly sets off the security alarm with the help of a boomerang until the "faulty" system is finally disabled.

Simon connives to "sell" it to him on condition that it never be displayed to anyone and that he never contact the Bonnet family again; Leland should expect to eventually be asked for payment.

He admits the Cellini Venus was his first heist too and reveals he is actually an expert consultant and investigator hired by major art galleries to enhance security and detect forgeries.

As Nicole and Simon prepare to marry, a collector who had earlier admired Charles's new "Van Gogh" arrives at the Bonnet residence and is warmly welcomed by the wily forger.

In a New York Times review, critic Bosley Crowther called the plot "preposterous" but added, "It is still a delightful lot of flummery while it is going on, especially the major, central business of burglarizing the museum.
