Charade (1963)

When a wife (Audrey Hepburn) returns home from vacation, she finds her apartment empty and her husband a murder victim. Apparently her husband was killed because of the $250,000 in gold he stole during WWII after double crossing his partners. But the money is still missing and her husband's killers threaten to kill her unless she tells them where the money is hidden. But she doesn't know! Stanley Donen's first rate romantic thriller is often referred to as the best Hitchcock film not directed by Hitchcock. It's chic and glamorous with a clever and amusing screenplay by Peter Stone and genuine Star power with Hepburn and Cary Grant in the leads and a trio of uniquely eccentric villains (James Coburn, George Kennedy, Ned Glass). It's a perfect blend of screwball comedy and high octane thrills and as shot by Charles Lang, Paris has never looked more appetizing. It's movies like this that made us fall in love with the movies in the first place. The elegant score is by Henry Mancini. With Walter Matthau and Jacques Marin.
