I suspect that you're already familiar with the film, but I'm horribly fond of Michael Curtiz's We're No Angels, which starred Humphrey Bogart, Aldo Ray, and a young Peter Ustinov. Bogart doing comedy is rare, and he's GOOD in this one. But then there isn't really a bad actor anywhere in the cast, including both Leo G. Carroll and Basil Rathbone. The humor is more often subtle and ironic than ROFL-inducing. But it's one of my favorite films.
