Deliberate mistake: Twice in this film Axel is shot at by multiple gunmen using automatic weapons at close range - and they all miss. In the Earthquake theme ride the bullets ricochet of the rails at Axel's feet. Why are they all aiming low? Why don't they raise their aim? In the park outside he hides behind a perfectly ordinary park bench and the bullets hit the wooden slats. Not one goes through the open spaces between them? I know bad guys can't shoot straight in the movies, but this is ridiculous ...
Continuity mistake: Just before Axel uncovers the printing press, the woman puts the map in the oky dokey suit, not his shirt. When he gets out of the suit, he does not pick up the map piece. In the vent he pulls the map out of his pocket, but how did the map piece get from the elephant suit to his pocket without him picking the piece up?
Continuity mistake: When Axel is in the Wonderworld tunnels he is spotted by security and they come after him. After Cooper jumps down from the rail, Axel's gun falls to the ground. It is in the middle of the walkway. Axel gets up and runs away and another bad guy is helping Cooper up but the gun is no longer in the walkway.
Continuity mistake: When Axel and Janice are looking at the blueprints of the park she rips off part of the blueprint at Axel's request. She then folds it in half with the print inside the fold then in half again. When she stuffs the folded blueprint into Axel's costume the print is suddenly on the outside of the paper when it had been folded on the inside.
Factual error: In an early scene, when Axel Foley is pursuing the bad guys' truck, he is driving a red sports car that is gradually being shot to pieces around him by the bad guys. At one point, his airbag deploys, momentarily impeding his driving. This is a prop error: It was much smaller than a real airbag, it inflated much more slowly than the real thing, and it remained inflated till he mashed it down (real airbags pop and deflate within a second).
Continuity mistake: After Inspector Todd is shot, Axel chases after De Wald and fires at the truck. When the guy at the back of the truck is shooting at Axel, we see multiple bullet holes near the truck's back right window, but in his close-ups the bullet holes are gone. The window frame's scratched paint differs as well in the close-ups. We know it's the same window because we also see him in the shot of the truck's interior.

Continuity mistake: At the beginning of the movie, while they are having a shoot out at the chop shop, the bad guys take the truck and rams a car out of the chop shop to make their escape. When they come out there's a car outside blocking their way. The truck goes at full speed into the right front side of the car. But when they cut to the next angel the truck hits the car on the rear left side and turns left to make their escape.
Revealing mistake: During the rescue on the big wheel, the people in the gondola behind Axel are obvious dummies, not only are they not moving in any shot but the man keeps his arm in the air pointing the wrong way the whole time.
