Continuity mistake: Optimus and the car Tessa is trapped in are caught in a net and are pulled up to Lockdown's ship. Cade then jumps and grabs onto the net whilst it is being raised. There is a brief moment where Optimus is not visible inside the from the net, before being visible again in the next shot. The CG artists likely forgot to add Optimus into the shot during post-production. (01:22:35)
Factual error: The location in DC has latitude and longitude both as N/S - longitude is an east/west factor. (00:13:05)
Continuity mistake: While singing in a duet with Miss Piggy, Céline Dion is wearing a dress with a strap over her right shoulder. Near the end of the song, the strap is suddenly on her left shoulder.
Continuity mistake: In the scene after The Celt defeats the big Thracian in a fight at the slaves' "new home", Master Graecus comes to get Bellator's explanation about the fight. After Graecus leaves, Bellator says "I'll remember you, Celt." Before Bellator says that, The Celt's left collar is below his shoulder. Just after Bellator says that, the camera cuts to show The Celt and his left collar is now on his shoulder. (00:19:25)
Continuity mistake: In the scene where after Peter gets his diploma and has a chat with Gwen, he is carrying a backpack on both shoulders. As the scene continues it switches to one shoulder then both several times. (00:15:50)
Revealing mistake: When Gandalf shakes Bilbo's hand it should be a lot bigger than his but it is the same. (02:25:26)
Factual error: The Mountain Dew logo seen in the stadium didn't come out until 1980, despite the film being set in 1973. The changes made in 1980 were subtle, but still distinct, especially the loss of the "wave" in the "D" and the smaller hole on the "a."
Continuity mistake: When Murphy pleads with Cooper to stay shortly before he leaves, as she shows him the message "STAY" on the notebook, in the first shot she looks down, but in the next one she looks at Cooper.
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: 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.
Other mistake: When Gator chuffs past Percy during the Our Tale of the Brave song, the second to last truck in his train is not rendered properly on the rails.
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: 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 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?
