Continuity mistake: Right in the beginning, Wade hops out a window from his home and starts walking beside it to the edge to climb to the next level down. As he starts walking he passes by another window with a curtain. It then cuts to a closer angle and suddenly the window no longer has a curtain. Also a wire appears on the wall in front of him. And you can tell it is the same house, not a time jump, as the rust at the top of the window frame is exactly the same. (00:01:15)
Continuity mistake: When Doctor Strange attempts to use the Time Stone on Ebony Maw, Maw ties up Strange telepathically and strangles him unconscious. Beside Strange is a police car and a motorbike tipped on its side. Maw then lifts the ground he is lying on, but the police car has been replaced by an SUV and the motorbike has disappeared. The shadows also change. (00:23:25)
Continuity mistake: When Ken Wheatley is pointing his tranquilizer gun at Zia after he shot Owen, he puts the gun in his left hand and uses his right hand to wave his men down, but mid wave, the camera cuts to a different angle and he is waving with his left hand while holding the gun in his right hand. (00:30:00)
Factual error: During the mid-credits scene T'Challa is addressing the United Nations about Wakanda's true nature. A Welsh flag can be seen among the other nation's flags, which would suggest that Wales is a separate nation from The United Kingdom - not the case.
Continuity mistake: The day after the robbery, Jacob is in his kitchen watching the news when his wife asks how he is. He says he's okay, he things and has his hand on his chin. In the next shot just before she continues talking, suddenly his hand is down. (00:23:15)
Revealing mistake: Fight in the toilet of the Paris nightclub: the presumed Lark rips out the sink's drain and begins assaulting Tom Cruise with it; Walker intervenes holding him, but the nimble Asian does a flip and brutally tosses him to the ground. As Henry Cavill is bent over before being snapped to the floor, on his back, you can definitely see a protective pad through the jacket. (00:31:52)
Continuity mistake: Trying to stop the bank robbery, the SWAT team arrive and they line up guns at the ready. It shows three of the four kneeling down with one standing as they take aim and start to shoot. In the next shot, suddenly all four are standing up and the SWAT Team armored truck appears beside them. (00:01:40)
Continuity mistake: When Phil heads to the Puppet Pleasure place early in the film, the positions of the shadows change around the vehicle parked out front in the close up, revealing the time laps between filming each shot. (00:06:30)
Continuity mistake: When Lara is in the locker room, she's eating an apple. She's taken at least two bites out of it. Then, when Terry comes in, she has the apple in her mouth which has not taken a bite out of and is a different apple. It has different coloring.
Other mistake: When Eddie is in his apartment and on the hunt for a new job, he uses his phone to text a contact while looking for work. His phone shows no signal meter. (00:23:10)
Visible crew/equipment: When Dmitri gets weapons from the back of the government vehicle: you can see the reflection of 3 crew members in the window of the truck. In the same shot you can see a crew member's gloved hand holding a flashlight inside the vehicle to light the scene. (01:16:00)
Continuity mistake: In the final fight, Deadpool says to Cable "did you feel that too?" and there's no-one behind them at all. Cable moves forwards to kill a guy on the ground, and a fraction of a second later, as Deadpool says "only best buddies execute paedophiles together" an orderly has appeared in the background, who gets shot.
Continuity mistake: Nice draws a line in the asphalt of the secret passage (cool idea, although there's no way that the bad guys can actually see that especially at a distance!). In the first overhead shot, there's a gap in the line. When the line is shown again next with the first baddie croaking before it, the line has already changed. (01:15:45)
Continuity mistake: When Jason lunges at Batman with his knife, there is a pile of garbage by the wall where he lands. In the first shot the barrel by the garbage is wooden. But in the next shot it's suddenly a metal barrel/drum. It then changes back to a wooden barrel again. (00:04:20)
Continuity mistake: Right after the space station explodes, Dr. Atkins sighs in relief and closes her eyes. She slightly tilts her face down, but still showing her eyes are fully shut. It then cuts to a side angle as the canisters beep before she looks over and her eyes are suddenly open. (00:04:40)
Continuity mistake: After manning battle stations, they hear a new contact and Glass puts on a pair of headphones. When he does, the way he holds the headphones changes from a full hand to one finger and vice versa. (00:23:16)
Continuity mistake: When it shows Mandy reading from her book, she has nothing visible sticking up from it in the wide angle. When it cuts to a close up suddenly the dollar bill she's using as a bookmark appears. It's first on the right side, then switches to the left side and further down. (00:17:30)
Continuity mistake: Right when the guards enter the home and the walls explode, Arthur swaps between having short curly hair to it being very long and straight.
Continuity mistake: After Gillick saves Isabel and they get into the car, the seats in the car don't have any head rests. But after they turn, and the camera shows them in the car again, the headrests are there. (01:02:55)
Continuity mistake: Velma reluctantly agrees to Daphne's idea to check out of the mysterious locker. She says "We'll come up with something." Right part of the frame, and in the background there's an extra (black kid with a plaid white shirt) that is simultaneously also eating at the table in the reverse shot. (00:31:15)
