An office worker (Ben Stiller) sees his best friend (Jack Black) strike it rich by inventing a spray that eradicates dog poop. The title is Envy
, and for 10 or 15 minutes, it looks like that’s going to be the theme, too. But Steve Adams’ script quickly goes roaring off on a hysterical tangent that has Stiller accidentally killing Black’s white horse and enlisting a disheveled wino (Christopher Walken) to help him try to cover it up. (Yes, it’s true: The film literally ends up beating a dead horse.) Stiller and Black have a few good moments scattered about more or less at random, and Walken once again has fun slumming in a role unworthy of him, but they and director Barry Levinson are unable to make sense of Adams’ insane mess. As the stars’ wives, Rachel Weisz and Amy Poehler are wasted.
