Continuity mistake: The area in front of the race's finish line is different when seen in the first race than when seen the second time as Parzival figures out how to get to it. When the camera zooms in on the Finish Line Gate in the first race, there is a train track or something similar right in front of the gate running parallel to the gate and wall. But as Parzival is driving backwards towards it in the second race, this track is gone, and instead there is a small drive path with small railing along it leading perpendicularly right to the gate. (00:15:40 - 00:27:15)
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 Maw then lifts the ground he is lying on, but the police car has been replaced by an SUV and the motorbike has disappeared.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.
Visible crew/equipment: When the dog owner gets out of his car to confront Jin, a boom mic can be seen reflected on the car window. (01:26:20)
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: 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.
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)
Visible crew/equipment: During the opening while Ray and Maggie are driving at night, you can see the lighting equipment for the green screen reflected in Ray's glasses. And throughout the entire movie, these green screens and other production lights can be seen reflected in his glasses in several different scenes. (00:04:00)
Continuity mistake: When Michel finds the pink thong in the laundry and thinks it's his wife's, he climbs on her bed chewing on them playfully before she tells him it's his daughter's thong. Between shots when she puts the mechanical pencil on his lips and tells him, the thong is suddenly hanging out of his mouth much further. (00:05:00)
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)
Factual error: Rhianna is watching a live feed of a man's office via webcam. We see a closeup of the screen. At the top it shows the filename being a ".jpeg." Jpegs are still image files, not movies, let alone live streams.
Continuity mistake: Constantine wakes up from a nightmare and sits up in his bed clutching his head. The window beside him has the blinds wide open with Big Ben seen through the window. But in the next shot suddenly the blinds are down covering a lot of the window. Also his bed posts change shapes. (00:03:10)
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: When they are first fighting, Will throws Ben onto the dishwasher. And as he rolls off it, there is a blue plate with a wooden spoon sitting on top of it. When Ben turns and grabs for a knife in the dishwasher, suddenly the blue plate is gone and replaced by various tupperware, and the wooden spoon is now standing up in a slot. (00:24:10)
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.
