Ryan Dunn only appears in archive footage in this movie. He had become depressed after developing a life-threatening blood clot during filming and contracting Lyme disease afterwards, so he declined to make himself available for interviews or commentary. In fact, he cut off all contact with his cast mates for years afterward, until shortly before Jackass 3 (2010) entered production.
Was briefly made officially available for online viewing to U.S. residents before the DVD release.
Only Jackass film to be released in December
