Revealing mistake: When Sonic and Tails arrive in Green Hills on the biplane, Tom and Maddie are looking up at them, but not focused on the same point. Instead, Maddie is looking to the left, and Tom to the right.
Revealing mistake: While in the helicopter, Alan's eyes do not align with the location of the Dreadnoughtus. Alan is looking to his far right before the helicopter even approaches the dinosaur and it is shown across the front of the screen. Alan's eyes then stay fixed straight ahead (even after passing the dinosaur), giving the impression he's looking at the dinosaur, but he would have needed to keep turning his neck to the right as the helicopter flew past in order to keep it in sight. (00:35:14)
Suggested correction: It's a common movie trope. The two things aren't happening in sequential order. They're happening at the same time. Alan isn't looking before the helicopter approaches the dinosaur...you're seeing the inside of the helicopter as it approaches and passes the dinosaur. They're happening at the same time.
Revealing mistake: While with Abigail, doors open to reveal a city and a plane behind which rises big jets of air that move Loretta's hair. However, the decorations on the table don't move a single inch (until several shots later), giving away that the city behind is CGI.
Revealing mistake: This happens in the second ceremony when Wolf didn't press the button to shut off the lights to steal the golden dolphin because of the good comments. Few seconds later, the lights shut off, and you can see that the meteor on the top disappears at the time.
Revealing mistake: Corporal Shah is tied and on a chair in the command center. He then receives a powerful blow to his left check, knocking him sideways and rendering him unconscious. But his glasses do not even move a millimeter.
Revealing mistake: The views to the right and left of the truck on the road did not flow in the manner expected if they were actually there (as opposed to using a green screen). Also, as soon as a "stop" sign could be seen to the right, the camera shifted to the driver, who kept driving as though the stop sign was not there. The structures to the right of the truck were blue but became white when the camera shifted to a front view (not using a green screen). (00:01:20)
Revealing mistake: In the wide view, the tree trunk is perpendicular to the level ground while Birdy and her cousin are standing. There is no large tree to the left, just a fence-like display of shrubbery parallel to the ground running across the rear of the screen. When the camera shifts to the girls sitting next to the trunk, they are made to appear as though they are sitting on a grade (not level ground), the background shrubbery runs diagonally across the screen, and a large tree is visible to the left. (00:32:38)
Revealing mistake: In the underwater view of the fish, the ice hole is almost perfectly round and the ice appears to be quite thin - nowhere near the several inches Jason and Ben have to chip away to reach water. (00:33:55)
Revealing mistake: During the scene with the ships hanging from the helicopters, Nate decides to fire a cannonball at the other helicopter as it's coming towards them. A standard cannonball shot from a 36 pound cannon that the Spanish used on their ships weighs 16.5 kilograms (the weight of a large full water dispenser bottle) but Nate tosses it around like it weighs nothing.
