Continuity mistake: When the landlady shows Judy to her "luxury apartment" note the position of the vertical deadbolt lock affixed to the front door and jamb, but the next morning when Judy leaves for the ZPD, as she unlocks the door the deadbolt lock has moved higher up on the door and jamb (note wallpaper). Additionally, just as Judy opens the door we can see that although the interior deadbolt is affixed higher, its key cylinder on the exterior side is much lower, which makes no sense, but then the deadbolt is back to normal.
Continuity mistake: In the bridge fight scene where Colossus and Negasonic Teenage Warhead appear, Deadpool tries to escape Colossus' handcuffs by severing his hand. The hand that he cuts off is his left, but when he jumps off the bridge the severed arm is on his right side.
Visible crew/equipment: After Doctor Strange experiments with the magical doorway in the Sanctum Sanctorum, he leaves it on a desert view and we cut to a shot panning across all the artifacts. At the very start of the shot on the right hand side of the screen is a crewmember standing in the shadows looking bored. Really blatant if you turn up the brightness, but easy enough to spot if you know what you're looking at. (00:56:00)
Revealing mistake: During the airport scene, after Tony tells Wanda that she hurt Vision's feelings, Tony and Hawkeye have their own banter moment. Then, when Hawkeye says, "Made you look," the next shot as the car is falling, Hawkeye is reversed; note his arm guard. (01:32:15)
Continuity mistake: Many times in the movie, Romit's hair changes from one shot to another. It goes from very short on the sides to long then back again. (00:59:30 - 01:11:20)
Continuity mistake: When Bodhi Rook is first introduced on Jedha, there is a fallen statue in the sand, first shown lying on its left, but at the end of the scene, the statue is suddenly lying on its right. (00:11:15 - 00:12:15)
Continuity mistake: In the footage inside the bathroom at Pope's, Kevin Hart is wearing a different sash from the rest of the party scene (or more likely, the same one but inside out by mistake). It's particularly obvious when he looks out of the window and the two patterns alternate depending on the camera. (01:04:50)
Continuity mistake: At the magic shop, when Daniel is reading out the list to Li, Daniel first has his right hand on the paper, but in the next shot, he is holding the paper with his left hand. (00:44:20)
Continuity mistake: Bill Pope just went off the stolen bike and is descending the stairs to the tube; people around him change completely between shots (he moves past a short haired woman dressed in black that is a few steps ahead of him, too). (00:03:50)
Continuity mistake: When the G.R.S. team is on their day off (9/11 anniversary), Tanto is seen video chatting with his wife. In the frontal shot of him, he's using a Samsung smartphone, but in the next shot, it changes to a Blackberry. This is done multiple times throughout the scene.
Continuity mistake: When the armored truck is headed to Raccoon City, there is a shot of 2 cars close together that instantly become further apart. (00:22:50)
Character mistake: When Mike's wife is watching the news about the oil rig on fire, you can see the TV with part of the U.S. map on it and 'Mississippi' is misspelled as Missisippi. (01:09:10)
Continuity mistake: When Sang-hwa is holding onto the first zombie he comes into contact with, he grabs onto the zombie's hair and some of its hair is in the gap between Sang-hwa's thumb and finger. In the next shot, that hair in between his fingers is no longer there. (00:25:45)
Continuity mistake: When the helicopter has crashed and the President and Banning are standing outside, Banning removes his radio and earpiece and throws them to the ground. The earpiece is back in the next shot. (00:40:00)
Revealing mistake: When Gabby and Fin are hanging off the building in Las Vegas, you can see that Gabby isn't holding on to anything in some close-up shots. (00:11:47)
Continuity mistake: After the mercenaries kill everyone in the desert, there are two guys looking at them using two monitors. The pencil below them changes from white to blue.
