Dean Martin turns on the charm -- just for you! -- in this PR photo from his 1963 film Who's Been Sleeping in My Bed?. The romantic comedy, directed by Daniel Mann, features a silly mishmash of mistaken assumptions as the wives of Dean Martin's friends start calling him for marriage advice. Suddenly everyone assumes that Dean is pitching woo with all of the aforesaid wives, don't you know. Dean's fiancee, Elizabeth "Bewitched" Montgomery, is heartbroken. Don't worry, it all ends well enough. But you can see why Dean is turning on the charm here.
