Other mistake: When Dr Grant and the children reach the perimeter fence, Dr Grant tries to see if he can fit through, to no avail. When he and the kids start to climb, however, it is quite obvious that both Tim and Lex would have been able to crawl through quite easily, and that only Dr Grant should have had to climb over. Partly this links to the mistake here, where the holes in the fence are much bigger in the first shot, then when he tries to widen them he's holding a different part of the fence where they're smaller.
Other mistake: When Gabe and the bad guy are fighting on the helicopter on the side of the cliff look carefully at the rotor shaft - you can clearly see that it has changed. Earlier when it was on the ground you see the shaft and the scissors on it. When it is upside down the scissors have vanished and the rotor shaft has a different look to it.
Other mistake: In the scene where Chris O'Donnell is going to rescue the two damsels being chased, he dismounts from his horse that is already tied to the cart and ties the horse with the other rein.
Other mistake: Before Jack's car jumps over the bridge, a van skids on the road. The first angle shows a thug firing at Jack, and the second angle shows Jack swerving to the left to dodge the bullets. The editing is all wrong here: The thug fires at the opposite lane to where Jack is, so he is really driving to where the bullets are.
Other mistake: They live in Los Angeles. When they left to go to Patusan, the scene showed a map and a toy ship with someone's hand guiding the ship along. On the ship they came from the Atlantic, through the Panama Canal, to the Pacific then onto Patusan. How did they start from the Atlantic when they lived in Los Angeles?
Other mistake: In the police car chase after the prison break, Mario lets go of the wheel to prove a point to Luigi. In doing so, their police car rams head on with a civilian car, causing the police car to ramp up and stop on top of the civilian car. Normally, this could theoretically happen. However, in that world, the police cars are fitted with a snow plow like thing on the front of the cars, with an angle to them. The way the cars hit, it is not possible for the police car to have hopped up on top of the civilian car in such a manner. If anything, the snow plow would have caused the civilian car to ramp up on the police car.
Other mistake: After Leonardo revives Yoshi, he picks him up, hugs him and touches heads with each other as they hug but Yoshi pretty much moved his head immediately and Leonardo continued sitting there as if their heads were still touching. It looks like the actor didn't realise the child moved away and they never reshot it. (00:48:15)
