The Thin Man (1934)
Husband-and-wife detective duo Nick and Nora Charles investigate a missing person case over the Christmas holidays – but the sleuthing takes a back seat to the banter between the couple in this screwball classic. "The next person who says Merry Christmas to me, I'll kill 'em," says Myrna Loy's Nora, perhaps not getting entirely into the spirit of goodwill to all men.
Johnny Depp's planning a remake of the series. He'd better not mess it up.
