Continuity mistake: In the opening credits, the guys are standing full depth in the giant shopping cart. When they get to the bottom, the cart most noticeably has a platform halfway down that the guys are standing on when they get thrown out. [It is mentioned on the cast commentary (by Bam) that they needed to raise it up because they were afraid of jumping out from so low down in the trolley. Still a mistake, but that's why it's there.]William Bergquist
Other mistake: In the Rube Goldberg Test scene, read the subtitles when Rip Taylor is talking. In the actual movie (where all we see is Johnny Knoxville coming out of the catapult) the subtitles have him saying "Oh, child." at one point. In the extras (where we see the complete Rube Goldberg Test), the subtitles show Rip saying "Oh, John." for the same line.
Trivia: Prior to the release of this film, Johnny Knoxville was reported to be, by an American tabloid, "so dishevelled" by a boy who died reconstructing "Big Wheel Craze" that he refused to make the movie or any more episodes of "Jackass." Two weeks later, the ad for the film was shown in the exact same spot in the paper.
Steve-O: We wanted to see if you would run.
Ryan Dunn: I'm not running anywhere with a toy car shoved up my butt.
Ryan Dunn: I'm surrounded by cacti, for fuck's sake... IT'S cacti.
Steve-O: It's cactus.
Ryan Dunn: Whatever it is, it hurts.
Question: On Yahoo movies, the description of this film says "including a climactic stunt of immense insanity." Now I have seen the movie, but I can't figure out just what stunt was the "climactic one". They all seemed quite climactic and very insane, so I'm wondering if anyone actually knows what stunt they were talking about, or if anyone has a good idea of which one it was.
