Continuity mistake: When Quill and Gamora first meet and get into a fight, Gamora grabs the Orb Quill is carrying and runs. Quill throws a sort of laser-based "lasso device" that snares her legs and causes her to fall. She pulls it off, and immediately in the next shot, it's vanished from the ground between cuts. It also had mechanical components, so even if the laser vanished, the mechanical pieces should still be on the ground.
Continuity mistake: When Classified is telling the penguins about the North Wind as Skipper eats the Cheesy Dibbles, the amount of cheese powder on Skipper's feathers differs between shots.
Continuity mistake: In the final police chase scene when Lou is getting out of the car to film the car accident, the left hand mirror of his car is intact at first then broken in the next shot.
Continuity mistake: As the two assistant workers walk away from the prison building at the end of the first day, Charlotte Gainsbourg's grip on her folders switches between shots.
Continuity mistake: When Eggsy is in the interview room at the police station, in a wide shot the tape recorder is on the table by itself, with nothing around it. Eggsy demands a phonecall, the police officer leaves, and Eggsy then reaches beside the recorder and picks up a cordless phone which has appeared from nowhere. (00:16:45)
Continuity mistake: At the start when the stall holder is throwing her sign in the bin, the way it's facing changes between shots. In one shot the straight edge is facing left, then right, then left again. (00:13:10)
Continuity mistake: When Thomas first arrives at the Clay Pits, Timothy can be seen with a train of trucks. In the next scene, they have disappeared.
Continuity mistake: About where she's heading 5 miles, in one shot Cheryl's (Reese Witherspoon) watch and bracelet are on her left wrist and in one shot they are both on her right wrist. Then throughout the rest of the film, Cheryl's watch and bracelet are on her left.
Continuity mistake: When Harper meets Ryan, who's out jogging in the rain, for the second time to recruit him into the CIA, the hood on Ryan's jacket moves between shots, most noticeably in the very close-up shot of his face. (00:12:00)
Continuity mistake: When the fairies are cooking and Aurora says she is moving out, for a brief shot the amount of flour on the left side of Knotgrass' brown apron disappears. Shot changes to the previous angle and the flour is back. It's not because of magic or due to a plotwise decision, it's a continuity mistake between two different takes.
Suggested correction: Considering the flour on her face is fading away, who's to say it's not on her apron as well?
Revealing mistake: In the news reel detailing the Kohinoor theft, a few headlines appear, and at least one persists on screen long enough to easily spot the inconsistency between headline and article (filler text presenting a new local magazine from the London district of Lambeth). (00:09:00)
Continuity mistake: In the scene with Crazy Cody, he holds a bottle of honey with his left hand. When he pours it on himself, the bottle is in his right hand.
Other mistake: When Lady Liberty's head rolls down the street behind Ellen, Mora, and Polly, it's a very distinctive street and there's a large white storefront sign 'Aleva' over a green awning that they all pass. Then after they drive off in the truck they're driving down that same street, even from the same direction, with that enormous head still after them. Additionally, that building with the 'Aleva' storefront and its awning has simply vanished the second time around.
Continuity mistake: When Lil gets up to pick up the carafe, her glass is, obviously, almost empty. The glass is refilled two shots later, before she pours (which happens later). (00:08:40)
Continuity mistake: During the gunfight in the arms dealer's hideout, Robocop enters brandishing his futuristic 'M2 Battle Rifle' which then immediately changes to an MP7 in the next shot. This error gets particularly blatant during the following shots from his POV, where he's shown still firing the M2 in his HUD, only for the scene to immediately cut to show him firing the MP7.
Continuity mistake: Wardaddy gives Norman the ultimatum of "him or you." When he does, he's pointing his revolver at Norman. Camera changes and he's no longer pointing at Norm. (00:38:30)
Continuity mistake: When Cooper draws on the board and talks about landing on water, his drawing changes between shots. (01:04:25)
Continuity mistake: At the end, John pulls the knife out of his side and it's got blood on it. Camera shows him starting to thrust the knife into Viggo and the blood has disappeared. (01:27:40)
Continuity mistake: During the whole conversation with Richard at the hotel bar, Olivia's handbag changes position multiple times between shots. (00:06:30 - 00:09:40)
Continuity mistake: When fuelling up the tank, Claudette can be seen with her hand on her head leaning against the hull of the tank. Camera changes and now she is stood and doesn't have her hand on her head. (00:11:20)
