Director Jeff Tremaine turns the MTV show "Jackass," in which Johnny Knoxville and his fellow stunt-loving pranksters perform daring and strangely idiotic feats, into a full-length film. Knoxville and friends -- including Tony Hawk and Spike Jonze -- are willing to do anything to amuse themselves and those around them. They wander Japan in panda outfits, wreak havoc on a golf course, perform stunts involving live alligators and more.
