Envy

Ben Stiller stars as Tim Dingman, a man whose envy grows as his friend and neighbor, Nick Vanderpark (Jack Black), becomes a millionaire after inventing Vapoorize, a spray that instantly disintegrates dog feces. After Tim's family temporarily leaves and he's fired from 3M, he concocts a plan with J-Man (Christopher Walken) to return a horse that Nick's dog, Corky, allegedly died from, but Corky is actually poisoned by a by-product of Vapoorize. Tim eventually comes up with a successful invention, Pocket Flan, and reconciles with Nick.
