Continuity mistake: When Shrek first meets Puss In Boots, Puss In Boots bursts out of Shrek's clothes "Alien" style leaving a tear. Then when we see them enter the Fairy Godmother's factory the tear is gone for the rest of the movie. (00:32:35 - 00:38:30)

Other mistake: Murphy lands the helicopter on a railway line so an oncoming train will destroy it completely, and this happens exactly on cue with huge, dramatic explosions and flying debris. Apparently the train driver doesn't think this is important enough to interrupt his busy schedule - he doesn't stop the train. We do not hear brakes being applied - the wheels would make a noise like the sky coming down - and the train doesn't slow down at all - it just keeps on going.

Continuity mistake: When Hooper gets his gear from below, after the explosion in the engine room, he runs to the deck passing Quint using the fire extinguisher. The camera pans from Brody, who stands on the bridge deck, to Hooper right below him. So where exactly is the tall iron ladder that leads up to the bridge deck in this shot? It should be behind Hooper, in front of the window, but it's gone. Don't fret, it's back in the following shots. (01:49:05)

Character mistake: In the meeting in 1984 when Jason Bateman first appears they have players on the whiteboard in the background. They have "Hakeem Olajuwon." He didn't put the H back in his name until 1991. So it should have been "Akeem Olajuwon." (00:08:40)

Continuity mistake: When Karl Urban is defending the Asgardians, the dust covers on his rifles vary between being open and closed several times. M16 dust covers are sprung loaded - they open on the first shot and have to be manually closed afterwards.

Kaecilius: How long have you been at Kamar-Taj, Mister..?
Dr. Stephen Strange: Doctor.
Kaecilius: Mister Doctor?
Dr. Stephen Strange: It's Strange.
Kaecilius: Maybe. Who am I to judge?

Continuity mistake: In the 'Gaston' song sequence, near the end, Gaston is sitting in his huge antler chair with Lefou. In the wide shot, there is a bear rug behind the chair. The camera does a close up of Gaston, then in the next wide shot, the chair is on top of the bear rug. Also, after this, Gaston gets up off of the chair and in the next shot, both the chair and the rug disappear completely. (00:29:20)

Question: In reality, do orcas actually understand English? Willy seems to understand Jesse when Jesse teaches him tricks.

Other mistake: After the first race, in the scene where Lightning is rushing out on the stage thinking he is the winner, loads of confetti is shot out when the King and Chick Hicks gets onto the stage. The confetti is then falling down, but not a single flake hits any of the cars. However, in the following shots, you can see plenty of it on the stage underneath the cars, even though they haven't moved.

Trivia: When the movie was first shown in theaters, the marquee read, "From the director of Animal House...A Different Kind of Animal." This lead many movie patrons to believe that it was another comedy film. People ran out of theaters in terror when they realised it was a horror movie.

Other mistake: Before Uncle Owen yells for Luke, if you look very closely, a fly can be seen on the lens (best seen on the special edition release). The fly was removed in the 2019 release.
