Other mistake: Early in the film, Jim Carrey is watching TV during a sports segment. He is watching Channel 7, the station he works for. This clip they showed was of actual WKBW sports director John Murphy. The clip they showed was taken directly from a real WKBW newscast, with the authentic news set, and graphics. However, when they show a clip of Ch. 7 News later, there are completely different graphics, and a completely different news set, both made for the movie.
Other mistake: When Mitch, Frank, and Beanie decide that they are going to have a party they say the party is on a Friday night. When they show the outside of Mitch's house you see the sign for the party and it says the party is on Thursday at 9:00. Then when Frank talks to the guys with the beer bong he says that tomorrow he has a nice Saturday planned. If the sign is right then he would have a pretty nice Friday.
Other mistake: Pintel and Ragetti fire the chain link cannonball, and it hits the square rigged mast aboard Interceptor. There's a shot of two men falling from the top of the mast, just before Interceptor's mast crashes onto the Pearl. They are not part of Jack's crew, who are all accounted for aboard the Pearl later. The only one of Jack's crew to die is the Asian man, when he's stabbed by a pirate and falls overboard. Nor can they be Barbossa's crew, because they haven't boarded yet. (01:27:00)
Other mistake: When Johnny and Mark save Denny from Chris R., they claim they are taking Chris R. to the police station. However, they re-appear in the scene almost immediately after (within 2 minutes of screentime, which is meant to be in real-time), with their having been obviously nowhere near enough time for them to have taken Chris R. to the police and done the appropriate interviews/paperwork.
Other mistake: In the scene where Paolo leaves the stage after everyone discovers that he can't sing, his bodyguard Serge stops him and Paolo suddenly loses his Italian accent. Paolo sounds very American when he says "You work for me, Serge."
Other mistake: When Mike goes to Marcus's house to apologize, as Marcus lets Mike in and they walk through the house you can see the corner of a very nice built-in pool through the glass doors, even though a large part of the beginning and the end of the movie take place in Marcus's '$3900' portable pool and its subsequent replacement. (01:34:20)
Other mistake: In the chase scene, where Johnny and Bough are chasing the hearse, when Bough and Johnny are discussing where the hearse went, Johnny says "They were heading south." Then he turns the steering wheel to his right, yet when it shows a view of the truck it turns to it's left. (00:22:15)
Other mistake: When the Angels are in the bar in Mongolia, and Alex is trying to get out of the trapdoor with Ray Carter, a guy falls over the trapdoor entrance. When Dylan tries to move him, and sits down on top of him, the trapdoor falls in. Wouldn't that crush Alex and Ray Carter? (00:04:55)
Other mistake: Towards the end of the movie, Clayton has two wounds visible on his face. These wounds keep changing length and shape throughout the scene.
Other mistake: During the beginning of the freeway chase scene, a "Maximum Speed 65" sign can be seen along the freeway wall in the slow lane that is facing the opposite direction of traffic. Freeway traffic in that lane would only be able to see it in their rear-view mirrors. (01:25:20)
Other mistake: During the jury selection montage the judge says 'Enter Lydia Deets as a juror.' Moments later, her profile is shown on screen and the lawyers accept her and the judge says 'Enter Miss Deets as a juror.' she has been entered into the list twice.
Other mistake: In the battle for Fredricksburg you can see streaks in the sky from jets.
