Eddie Murphy and Ben Stiller carry on a long tradition of onscreen odd couples when their characters team up to rob a Wall Street shark in 'Tower Heist.' Murphy plays a two-bit thief in the Brett Ratner-directed film; Stiller, a by-the-book hotel manager who gets pushed to his breaking point after finding out his pension has been lost in an elaborate Ponzi scheme. These two childhood friends have nothing in common... except a final goal: stealing $20 million. Will they work out their differences and succeed? Probably! At least if you go by the long history of Hollywood odd couples. Ahead, 13 great ones.
