Other mistake: When everyone is on the road leading to Silver City, near the end, about four of them are behind one another on the road. When it cuts to the radar owned by Sinclair, it shows all of the dots (which represent the people) all spread out around the big star which is train station, when in fact the dots should all be in a line behind each other, just like they are in the cars.

Continuity mistake: There is a shot of Blaine as he lays on the Cadillac's roof during the balloon/cow/keymaker/car chase. This shot is specifically for when Blaine snaps the hood ornament off of the Cadillac by accident, then stares at it in his hand. In the next shot of the car, the ornament is back on, and it stays on for the remainder of the scene.redbaron2000
Revealing mistake: At the end whenever we see a shot of the large crowd from the stage point of view look closely.You can see how the image of the crowd has been tiled because people are transparent. They must have filmed a small section of the crowd then duplicated it to make it appear that there are thousands of people there.
Factual error: When the brothers are both in the pond and one of them comes up covered in pond weeds, notice a few places on his body, for instance the side of his head, he has a plant attached to him called Water Hyacinth. This plant not only does not grow in the South West, but also floats and you can see that there are none floating anywhere on the pond, especially in the middle where he landed.Sol Parker
Continuity mistake: When Seth Green and his brother are chasing the keymaker, they fly over two embankments. In both shots, upon impact they break the A-pillar in the car, resulting in the nose of the car pointing upwards and the area directly under the windscreen bent down, common in a stunt like that. In the next shot of them racing along the paddock, the car is perfectly normal.
Deliberate mistake: In the infamous coin toss scene, Cuba's call is disputed. However, it appears that the coin on the ground is in fact in agreement with his call. However, he explains later that they use a special commemorative coin that is hard to read as it may have what appears to be a head on both sides. Therefore, the coin may have had a head come up, but it was agreed that that side would be 'tails'.
Continuity mistake: In the scene where everybody is racing downstairs, as they all fall in the corner you can see Vera is wearing high heels. Later on in the film, especially noticeable at the rocket car scene, she now has flat shoes on. What, did they take a trip to the shoe shop during their frantic race to Silver City?

Continuity mistake: At the monster truck ralley, in the first shot as the monster truck revs up, ready to jump the ramp, look at the huge advert signs behind it. One of them has "PowerBar" written on it, but in the second shot as the truck roars over the ramp, the same sign is now totally different. (01:23:25)Hamster
Continuity mistake: At the start of the scene where the taxi driver leaves Owen out in the desert, in the first wide shot of them driving on the road, the road has no markings on it. In the next shot of inside the car, you can clearly see out the back window of the car that the road now has double yellows lines running across the middle of the road. (00:35:40)Hamster
