Specifically, Jude Law’s ass in I ♥ Huckabees, which I got to see in a free preview screening last night. The tagline is “An Existential Comedy,” which fits. Like the other David O. Russell film I’ve seen, Three Kings, it swung briskly from flat-out hilarity to surreality to earnest dismay and back again. This movie strengthened my conviction that one of the greatest assets an actor can possess is the unwilligness to risk total embarassment, what with the swamp sex scene between Jason Schwartzman and Isabelle Huppert, Mark Wahlberg ranting about the evils of petroleum and hitting himself in the face with a big pink rubber ball, Naomi Watts banging on plate glass with her ass, and Jude vomiting into his cupped hand during a board meeting. Amazingly, everyone pulls it off.
