Revealing mistake: When Lightning, Cal and Bobby enter the pit row, the King's model is merged with the one from the crew chief next to him. (00:03:05)
Revealing mistake: After Rey lifts the rocks away from the back exit of the bunker, you can see C3P0 briefly as he bumps into the rock in front of him while exiting the cave, and the rock moves slightly. Also, the rocks that fell over the exit don't match the surrounding terrain at all while piled up as they are smooth like river rocks, but when we see them lifted up by Rey in the subsequent scene, they are rougher and look nothing like they did before (as well as being pretty lousy CGI).

Revealing mistake: The woman who died giving birth blinks as the doctor walks away. (00:13:55)
Revealing mistake: During the fight in the forest with Heimdall and Hela's soldiers, he uses the sword but the tree is cut before the hit, and the soldiers on the right fall before the hit too.
Revealing mistake: When Taserface is threatening Rocket, Rocket is making eye contact. Taserface, meanwhile, is looking at the space between Rocket's ears.
Revealing mistake: During the bank chase at the beginning the bottom plank is a material skirt which moves forward and backwards revealing in some shots the wheels underneath the bank.
Revealing mistake: During the underwater scenes the light appears from below and above but it's underground and should be pitch black, suggesting studio lighting being used.
Revealing mistake: Xiang storms the CIA headquarters at the beginning of the movie and fights off a dozen of agents and executives. Check out the moment when Toni Collette comically pokes her head from under the table and Donnie Yen kicks two agents. The second agent is charging at him with his fist raised, but blatantly stops with no guard raised, waiting to be spin-kicked into oblivion. He was also seen hopping up but when they get blasted away it's the burly Asian guy who is level with Donnie Yen, not him. (00:09:35)
Revealing mistake: At the beginning as Noah's vehicle is reaching the edge of New America, there is a shot of a drone swooping down over a hill to follow him. As the drone comes onto screen, there is dust and debris animated to come up at the camera as it blows around its environment. However this small bit of superimposed bad special effects is the only thing it seems to affect. It swoops down right next to some tall dead grass and other plants, on a dusty hill. But not one item of the real environment is blown or even moves in the slightest from this drone passing by it from inches away. (00:01:30)
