"Envy" - Barry Levinson directed this comedy in which success has a rather surpri sing effect on two old buddies. Nick Vanderpark (Jack Black) and Tim Di ngman (Ben Stiller) are best friends and next-door neighbors who work to gether at a sandpaper factory. Nick and Tim often find themselves wishi ng for something more from life, and Nick has a habit of dreaming up har ebrained get-rich-quick schemes that u sually end in disaster. Tim is pa rticularly appalled by Nick's latest idea, "Vapoorizer," a cleaning prod uct which will make pet fec es magically disappear, but to their shock, it turns out to be an incredible success, and before long Nick is wealth y beyond his wil dest dreams. Tim, however, is still the same guy gettin g by in suburbia he's always been, and soon Tim finds himself bitterly r esent ful of his old friend. As Nick gets richer, Tim gets angrier, and he develops a drinking problem. One night, in a bar, Tim meets an eccent ric drifter (Christopher Walken) who offers him some not-so-friendly adv ice on getting even with his old friend. Envy also sta rs Rachel Weisz a nd Amy Poehler as Tim and Nick's much-put-upon spouses.
