Comedy is funnier when it rebounds off a hard reality, and the money woes underpinning "Tower Heist" give the caper a solid bounce. It's a stunt-heavy comedy, but its world resembles ours more than most movies do. A working-class "Ocean's Eleven" reflecting our economic mess is a vision a lot more relevant - and funnier - than comedies about men in drag, competitive bird watchers or talking zoo animals.
