Continuity mistake: Look carefully at the brochure Frank has about the Buffalo Chicken Wing festival, the building pictured is the same building as his daughter's school (seen earlier in the movie).
Suggested correction: While the buildings might look similar, they are different buildings. The school has 3 levels with rectangular windows with a pyramid top while the building in the brochure only has 2 levels of non-rectangular windows and more of a dome shape on top.
Continuity mistake: When Jesse and Frank are telling the doctor that his son was killed (right in the beginning of the movie) Jesse gained a lot of beard growth in five minutes. When they are outside talking to Zee, he has just a light beard, and then when they go inside he has a heavier one.
Continuity mistake: Nellie is called into Captain Brackett's office one day. Later, one of the girls asks her "What did the old man want this morning?" However, the scene at night between Billis and Cable shows that a whole day and night must have passed in between these two scenes. Therefore the nurse should have asked "What did the old man want yesterday?"
Continuity mistake: When Vince gives his speech to the Kuvuki people there are two men standing behind him. In a panorama shot at the end of the speech there is nobody at that spot. (01:24:25)
Continuity mistake: Brubaker slides home head first. When he is coming to the dugout, he gives his team mates high-fives. It can be clearly seen that the front of his uniform is clean and spotless.
Continuity mistake: At the end of the movie when Steve and Anna are in the boat going across the harbour, in the background is a Shell petrol station on the shore. The boat is travelling from left to right across the screen, but as the camera shots change from Steve to Anna, or both at once, the Shell sign keeps changing its relative position to the boat.
Other mistake: In the beginning, the girls arrive at the airport in Chicago and you can see a billboard in the background. Then the credits roll and they land in the sunny Bahamas and as they are driving away in the limo, the same billboard can be seen in the background. Guess they were on a tight budget and had to computer generate the snow over a scene filmed in the Bahamas.
Continuity mistake: Just after Knoll has been beaten up we see Elwood sitting next to him. As Elwood switches on the light, we see that the left side of Knoll's face is covered in blood. After Elwood applies the bandage, the blood on his face has changed with much less blood on the left side. The blood was never wiped off.
Revealing mistake: When Jessica and Helen are arguing outside the dress shop, there are 2 girls crossing the street in the background who blatantly stop to watch the scene.
Continuity mistake: After Ciki gets out of the trench to get a lighter from his pal's bag he lights a cigarette while he is still squatting outside the trench. In the next shot you hear the lighter snap shut, and Ciki is leaning against the wall of the trench. (00:12:30)
Continuity mistake: There is a scene when a girl knocks on the door of the house of her friend. She opens and in the background you can see another girl doing nothing. The shot later she has disappeared.
Continuity mistake: When Max punches a hole in the wall after hearing about General MacArthur being called a commie, the hole in the wall changes height and size as the camera angle switches back to him from showing the reaction of his writers.
Continuity mistake: When Matt Dillon is talking to Michael Douglas at the bingo hall, the caller calls out "O 18". Later in the film during a different game, it's called again. All Bingo junkies know that the "O" numbers are 61 through 75.
Continuity mistake: When the man is laying out the photo files on the desk, he puts down files one, files two, and then file three. In the next closeup the position of photo film number three has changed.
Continuity mistake: In the scene at the little bar Bruce Willis kicks Billy Bob Thornton's chair over. Kate Blanchett picks Billy Bob up and tries to dance with him. A different angle shows Bruce Willis still at the table and the Billy Bob's chair is now upright.
Continuity mistake: When Margot is telling the story about how she lost half her finger it shows her putting the log up to be cut and it shows her left hand on top of the log. But when the shot moves out to show when her finger gets cut off, her right hand is suddenly on top of the log.
Continuity mistake: Towards the end of the movie during the play, Kelly goes backstage during intermission, and her hairstyle and color has changed. (According to DVD commentary, it was a pick-up scene and she had already started filming Spider-Man. That's why her hair was now red. Still a mistake, but there's the explanation.)
Continuity mistake: When TJ jumps in the dumpster at the school to hide from the guys in suits, he sees two guys and another who's dressed up like Principal Prickly in his normal shabby suit, but then a second later when he takes off his Prickly mask he's in a black suit.
Continuity mistake: At the end, right before Matty is going to toss his keys inside the Cadillac, the window is only down a tiny bit, but when he actually tosses them the window is all the way down.
Continuity mistake: When Mario walks out of the bus station to meet his auntie and cousin, he is holding 3 bags. 2 rucksacks and a sports bag. The sports bag is all black. When he arrives at his auntie's house, he takes his bags out of the trunk. The 2 rucksacks are the same, but the sports bag has gone from all black, to red and green. (00:45:10)
