Revealing mistake: On the ice the tank is firing - in slow motion we see empty shells are littering the area. The shells have crimped ends, revealing them to be blanks.
Revealing mistake: When Chucky's disembodied head tries to bite Andy in the beginning, watch closely. When the plaque he's mounted too leans forward suddenly as Chucky snaps at Andy, you can see a rod underneath of it, which was used to make it move and lean forward by the puppeteers.
Revealing mistake: During the car chase when the car gets hit by the truck and goes into slow motion you can see the roll cage inside the car.
Revealing mistake: In the beginning of the movie, when John get his Mustang, he starts accelerating deliberately to hit one of the cars (black sedan), but right after the odometer scene (where you see the gas going up) you actually see the car is stopped. It is pretty obvious. (00:09:30)
Revealing mistake: Throughout the film, the characters can be seen to impossibly pivot on the rigging suspending them in the air in a manner inconsistent with zero-g as they move through the space station.
Revealing mistake: When Mae is on the phone with her parents, there is a camera feed shown of the parents, and in the bottom right hand corner, a camera feed of Mae. When Mae is holding the phone, her hand is visibly seen shaking and readjusts the phone at numerous points, the camera feed of her shown on the phone remains completely still throughout the call. (01:13:05)
Revealing mistake: To kill the second and third guy at the food court, Eddie does a rather unlikely slide across the floor. His shirt is pristine even in the back, despite having sailed across soda. (00:57:40)
Revealing mistake: The bartender (Kateryna Korchynska) offers Ethan two lattes on the house. She hands them to him, and he walks out. No opacity from the liquid can be seen inside the plastic cups, and when he is moving away from the counter he leans forward quite a bit, showing the inside of the cups, squeaky clean. (00:08:00)
Revealing mistake: When Will and Danny are walking in the woods to go deer hunting, it is raining on the right half of the screen but not the left. (00:19:04)
Revealing mistake: When Hennessy is confronting McGrath, he shoots 3 bullets from his pistol and also hits him in the face with the butt of the gun. There is no magazine/clip in the pistol. (01:19:30)
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: When Richard and Stan are driving across the desert, there is a shot of Stan driving the SUV. The number plate and Range Rover logo appear to be reversed and the driver seat is shown on the right hand side instead of the left hand side, revealing that the shot has been flipped. (01:04:40)
