If you like classic comedies but have seen the "usual suspects," my wife and I really enjoyed "The Devil and Miss Jones" with Jean Arthur and Charles Coburn. I thought I'd seen them all but not this one. As far as that goes, *any* Jean Arthur movie is worth watching. ;-)
If you have a hankering for vintage musicals, don't miss "Romance on the High Seas." I know, I know--Doris Day?!? It was her first movie, extremely well directed by Michal Curitz, who discovered Day and could direct just about anything, including "Casablanca" and "Yankee Doodle Dandy." Day is charming and sings like an angel, and Oscar Levant delivers some terrific one-liners. It's quite fun.
