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 Richard punches Stan, a blood splatter comes from his nose. He falls back and blood is over his face and his hands. Just after he is first punched, his hands are already covered in blood as he is falling back, before he touches his face. The blood was most likely applied to his hands separately before filming the scene as it was never visible on his hands at any point earlier on. (01:03:35)
Revealing mistake: When Banderas and co set ablaze the SUV dropping the flaming sofa on it, the man coming out of it is wearing a full fire retardant suit. (00:38:35)
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: 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: The DJ dude is trying on the super gloves, but loses control and punches a hole in a hatch. Before the shot changes and we get to a close-up of the hole in the metal, you can see Kris Wu pull his arm back and the not-so-metallic parts of the door being pulled back, caught in the denim of his jacket like carton or foil.
