Scheming inventor Nick Vanderpark (Jack Black) becomes an instant billionaire when he creates a spray that vaporizes doggie doo. And as best pal Tim Dingman (Ben Stiller)-who turned down a chance to get in on the deal-becomes more and more envious of Nick's newfound wealth, the stage is set for a side-splitting showdown. Barry Levinson's dark comedy co-stars Rachel Weisz, Amy Poehler, and Christopher Walken. 99 min. Widescreen; Soundtrack: English.
