Character mistake: Selena Gomez drives into town in a fully restored 1967 Pontiac Le Mans, which is a long box shaped car. However, when confronted with Bill Murray and Adam Driver, Adam Driver complements her on her 1968 Pontiac Le Mans, which is a completely redesigned shorter curved body style. The two look nothing alike.
Factual error: When it's 00:00 on January 1st, it's not night in Sydney, it's 11 AM. When they 'reveal' stuff at the end of the movie, and they show that things happen exactly at 00:00 in the night in London, it can't possibly be dark in Sydney, Australia.
Suggested correction: It shows that Sydney is at dusk and is becoming dark, so around 5pm-6pm-ish, not 11am during the day.
Continuity mistake: When Craig is sitting on Elroy's couch, he lights a joint and puts the lighter on the table. It disappears in the next shot.
Continuity mistake: In the bowling alley, 'Pal' comes over to speak to Tia. During their conversation, the camera pans to Maisie throwing a bowling ball; however Tia is now sitting alone. Pal has disappeared. (00:40:10)
Factual error: I work for a television channel in 'daytime serial' production and I can assure you that no actor is going to secure a recurring speaking role in a soap opera unless a comprehensive insurance policy has been secured. (This applies to feature films, too.) This will inevitably involve a medical examination. I'm afraid Mr Dorsey's plans are going to become dreadfully unstuck the minute he drops his y-fronts in the doctor's surgery. (No, he can't find a compliant or bribeable doctor - the insurance company will always use their own people.).
Continuity mistake: When the devil is falling apart and his 2nd ear falls off, he tells Nicky he cannot hear him, and asks the demon by his side who catches it to put it back on his head. But towards the end, when the devil is reduced to no more than a mouth and 2 arms, he is able to have a conversation with his demons about what's going on and hear them perfectly. (00:52:05 - 00:58:50)
Suggested correction: Its not clear that they are actually having a conversation, he is just a mouth and two arms that can only talk and hold itself up. They respond to him because he can hear but he doesn't even respond to them. Its not illogical that Satan was talking to himself while deaf and falling to bits.
Continuity mistake: At Riley's Garage, when Troy and Chad are about to rummage through the junk looking for the radiator cap, Troy raises his arms and his boxers are light grey, but next shot when he lifts the truck's hood his boxers are black. It's also noteworthy to mention that during "Boys Are Back," young Troy is wearing patterned boxers, though all other clothing is identical. (00:53:45)
Continuity mistake: On the small sand spit, when Jack, Elizabeth and Barbossa meet with Will, Beckett, and Davy Jones, the leather cuff Jack wears on his right hand actually disappears and reappears twice during the meeting.
Continuity mistake: When Chris Farley is pretending to be a Chinese cook at that one restaurant, cooking, the brown spot on the stove keeps on changing size.
Continuity mistake: When Sonic and Tails are fighting metal Robotnik, he shoots glue at Tail's tail. Tails says he can't fly to help Sonic, but when he gets the piece of concrete to surf across the water on you can see that his tails are not glued together.
Factual error: The terrorist with the AK47 is unaware of the fact that a Harrier is hovering just outside the window until he slowly turns and see it there. He does a double take when he sees the Harrier just five metres away! A Harrier is an incredibly loud aircraft; you can hear them from three kilometers away. At that range the floor would shake with the noise and he would have been in no doubt whatever that he had been under attack for some time.
Plot hole: Spoiler: At the end of the film we learn that the girl is the wild animal, having been saved by the same doctor. Yet at the restaurant she is wearing a bare back dress and does not have the giant X-like scar on her back, like he has or the model has, who the doctor marries at the end.
Continuity mistake: Tom and Huck have just swore they won't tell about the murder. Tom writes an oath, and Tom and Huck slit their fingers to sign it in blood. Tom, slits the index finger on his right hand. He signs the oath, however, with his index finger on his LEFT hand.
Continuity mistake: When the two brothers are frantically trying to get out of the car because the monster truck is barreling toward them (in slo-mo), you will notice that the tongue ring is missing from the one brother's tongue. Odd mistake seeing as his character is centered around the tongue ring. (01:27:05)
Revealing mistake: When Sonny is on the payphone, you can see Julian mouthing something to the guy on the payphone behind Adam. The guy is giving him instructions.
Continuity mistake: When Meryl Streep "blasts" Goldie Hawn with the shotgun and Goldie falls into the pool of water, she falls in backwards. However, when we see her get up, she is getting up from a face-down position. (01:05:25 - 01:07:10)
Other mistake: When the nanny comes home with the tags, they call Jewel to get hers first. Jewel has a penis.
Continuity mistake: William H. Macy makes dinner plans with the Mayor and writes "Dinner with the Mayor" on the dry erase board in his office. He writes "Dinner w/ the Mayor" in the "Tuesday" slot. Then an intern comes in and accidentally wipes the appointment off the board with her shirt. Macy yells at her and tells her to rewrite the appointment on the board. The whole premise of the joke and pretty big part of the movie is that the intern rewrites the appointment in the wrong day, thereby causing the Hollywood people to miss dinner, enrage the Mayor and his wife and have the town turn on them. When the girl walks away however, the appointment is clearly rewritten in the correct day (Tuesday). This ruins the whole misunderstanding because although the appointment is in the wrong day later in the movie, at the moment the joke is supposed to be set in motion, there is no mistake.
Continuity mistake: Professor Sheldon 'Shelly' Oberon sprains his right ankle when escaping the baboons by jumping to another bridge. Ming Fleetfoot wraps his left ankle later on when they are by the river. (01:11:38 - 01:14:00)
Continuity mistake: During the detention scene, the teacher comes in and you can see there isn't anything on his rear end. As he leaves, you can see toilet paper hanging from his rear. This was because a scene never made it into the movie where the teacher's office is in the mens restroom. Also confirmed on cast commentary.
