Revealing mistake: At the point where someone gets a small bruise on the upper arm, the crew are all in a pile and thrashing about on the floor. There are 5 pairs of legs instead of 4. Arthur is in his pajamas, Zaphod is in orange trousers, Trillion is lying on top of Ford and Ford is too far away for them to be his legs. [The fifth pair of legs belong to the person playing zaphod's third arm - doesn't mean it's not a mistake, but that's where they come from.]
Continuity mistake: The small horse trailer hitched up to the back of Ralph and Pam's station wagon has the license plate number, T-479E5, which is visible a few times, then when Ralph is on King's property he gets a vision of Desperado's location, and just as Ralph does his vanishing thing, one of King's horse trailers has the same license plate with the number, T-479E5. (00:13:50 - 00:33:50)
Continuity mistake: During the Tag Team title match only Jackie's wearing knee pads. Yet later in the match Marie's suddenly gained her own pair of knee pads.
Visible crew/equipment: When Miss Hawk is speaking to Edward by the well, the boom mic can be seen in the top right of the screen.
