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.
Jackass: The Movie (2002)
1 other mistake
Directed by: Jeff Tremaine
Starring: Johnny Knoxville, Bam Margera, Chris Pontius, Steve-O
Continuity mistake: The opening scene in the shopping cart must have been filmed in two places. At one point you can see the end of the road, which is just a brick wall, but they crash into a market.
Johnny Knoxville: There's no such thing as failure, Steve-O... One thing I know, is good tightrope walking.
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.
