Director: Stanley Donen
Stars: Cary Grant, Audrey Hepburn, Walter Matthau

Romantic comedies were better in the '60s for one reason: spies. Movies like 2009's Clive Owen/Julia Roberts' vehicle Duplicity have tried to capture the magic of romantic mysteries like Charade, but to no avail. For one thing, Owen and Roberts are Grant and Hepburn; they're just that pair's stepchildren.

In Charade, Hepburn plays a Reggie Lampert (already off to a great start with that name), a woman whose life has taken two unexpected turns. Her husband is dead, and she's just met the definition of charm, Cary Grant's character. (FYI: This is always his character.)

From there, the film kicks into high gear, with laughs, suspense, and heavy petting. This is the early '60s, after all.
