Gambit (2013)

An uptight art dealer teams up with an eccentric Texan to put one over on his boss in Gambit (2012). Nebbishy curator Harry Deane (Colin Firth) is an expert in two things: fine art, and taking abuse from his asshole boss Martin Zaidenweber (Stanley Tucci). But he's got a plan that will change everything. In order to con English gazillionaire Lionel Shahbandar (Alan Rickman) into buying the fake Monet that will be Harry's ticket to the good life, he recruits rodeo sweetheart PJ Puznowski (Cameron Diaz) to serve as his honeypot assistant. But when Harry finds himself falling for PJ, things get significantly more complicated. Although Cameron doesn't get naked, her skivvies scene will really twirl your lasso.
