Continuity mistake: When Del comes out of the passenger side of the dairy truck, he is seen with a black eye, for no reason. The next scene, it is not there. It is there again when he admits to being homeless.
Continuity mistake: Right before they rob the police car, a Boeing 747 (four engines) is seen in shots of the plane coming into land. When the plane is shown from behind, it is a Boeing 767, with only two engines and fewer main landing gears. (00:30:10)
Continuity mistake: During his conversation with the director, while discussing his costuming, Dalton's hair changes from messy and curled to gelled up and straight.
Continuity mistake: After Gerry gets smacked in the face by the 'broken' suspender clasp, we see the silver clasp land under the dresser. Yet, when he's moaning and lifting his leg to get onto the bed, we can actually see the clasp still intact on the front suspender that came loose, which is dangling right behind him (just look between his legs). Of course, in the next shot, that clasp is gone. Since the silver clasp is one of the plot points, this is bizarre to say the least. (00:11:10)
Continuity mistake: Peter is in Lara Jean's kitchen, wearing a jacket. Her dad comes home, he and Peter shake hands, and in one brief shot Peter is not wearing a jacket but a plain short sleeve top. Angle changes again and the jacket is back. (00:39:00 - 00:40:15)

Continuity mistake: Towards the end of the movie, when Joey Nova is trying to get out of town, he sells his football ring to the drug dealer, but in the final scene he is clearly shown wearing the ring when he points the gun at his father.
Continuity mistake: In the exterior front shots of Elliott's house there are some significant changes to the landscape in different shots. For instance, the two lampposts at the bottom of the driveway change to an entirely different style in some shots, and the huge garden boulders repeatedly vanish and reappear. Also, note when Michael takes off on Elliott's bike to go search for ET, the in-ground lamppost that should be beside the mailbox has vanished, but it reappears when all the government agents are setting things up outside the house.
Continuity mistake: When they are looking at the house and they get out of the car, the one man on the passenger side leaves his door open. When they walk to the side of the house and come back to the front, you can see the car in the background and the door is shut.
Continuity mistake: When a man attacks Hoffa in court, Hoffa's son attacks him, then in the next shot he is not up from his chair. (01:22:47)
Continuity mistake: When Emily Watson first strokes the tiger on the table her watch says 11:15, on the next stroke her watch says 11:20. Then the doctor hands her the stethoscope and her watch says 12:00.
Continuity mistake: During the infamous leg un-crossing scene when Sharon Stone is being interrogated, a cigarette in her hand disappears and then reappears.
Continuity mistake: The owner of the Cleveland Browns drives from NYC to the Teterboro Airport (12 miles from Midtown Manhattan), flies to Cleveland (450 air miles) and drives to the Browns facility (16 miles) in the time it takes the 2nd, 3rd, 4th and 5th picks in the 1st round of the NFL draft to be made.
Continuity mistake: In the final scene where Roxie and Velma are dancing in the concert hall, Roxie is on the right and Velma is on the left. They then turn around, and from behind (same point of view as before) they're suddenly the other way around. (01:44:20)
Continuity mistake: During the Xmas day scene, Markus receives a Sony portable CD player as a gift from Will. However, before the gift's unwrapped, the Sony box is visible on the table. (00:51:45)
Continuity mistake: When swimfan85 is trying to talk to Ben and he tells her he has homework to get done, she is talking with the nick name swimfan85 but when she signs off it says "swimfan has signed off." They forgot to add the 85.
Continuity mistake: When the real 'manager' comes outside to yell at "Mr. O'Donnell', you see the manager walk back into the club. If you look in the background of the next shot, you can see the manager walking through the door again. (00:13:25)
Continuity mistake: Agatha's nightgown strap switches between hanging down on her arm, or being up on her shoulder, normally.
Continuity mistake: When Eddie falls through the floorboards, you can see his arm looks perfectly fine and is unbroken in a few quick shots. After the movie cuts back to him a few moments later, suddenly his arm is badly broken. (01:20:30 - 01:23:25)
Suggested correction: It's for effect to show they were hanging out around the airport for more than a bit.
There's no evidence this was meant to be a montage scene of various planes. The cuts they did have in the first angle were of the same plane getting closer to build suspense. Same for the other angle. Plus, there's no scenes or shots of "them" waiting.
