There's plenty of naked and half-naked middle-aged men to choose from in the amusing new trailer for Gambit, which features a pantsless Colin Firth going toe-to-toe with a buck-naked Alan Rickman -- and a big-grinnin' Cameron Diaz sporting a Texas twang thrown in for good measure. Watch the trailer!

A remake of the 1966 caper film starring Michael Caine and Shirley MacLaine, the updated version (with a screenplay by The Coen Bros.) finds Colin sporting some Caine-inspired specs as a Brit art curator who decides to get revenge on his abusive boss (Rickman) by conning him into buying a fake Monet. Diaz plays an eccentric and unpredictable American rodeo queen enlisted to pull off the ultimate switcheroo.
