Other mistake: During the baseball game, Ryan's team was in the field first meaning they were the home team. After Chad scored giving his team the lead, Ryan's team should have batted again since, according to baseball rules, home team bats last.
Other mistake: When Beverly Farley asks her son, John, where he has, she states that she thought John was going to ride together with her and Mr. Woodcock, to the awards ceremony. But later, when she leaves the ceremony she is mad in her own car, and Mr. Woodcock's car is right next to the awning. So Beverly and Mr. Woodcock did not drive there together. (01:00:20 - 01:06:10)
Other mistake: In the scene where you first see Tracy in class, one of the boys speaks and the subtitles reads," Ms. Whimsy, I can't see the board again." When Tracy says it, the subtitle reads Wimsey.
Other mistake: Two mistakes in one scene. Continuity Error: As Dewey's father is dueling with Dewey with a machete, Dewey's father cuts a ladder in half. Later in the same scene, you will notice that the ladder is whole. The second (Revealing Mistake) shows a wire leading up from the barn floor to Dewey's father's bottom half, supporting the effect. (01:12:10 - 01:13:05)
Other mistake: Just before Debbie takes her shirt off after Walter has given all of the Playpen girls suggestions, one of the girls says "It's hot in here." (probably Debbie, but it doesn't really sound like her), but Mona doesn't start having an orgasm, when "in" is supposed to start it. (00:33:50)
Other mistake: In the scene in the beginning when Chazz Michael Michaels is being introduced, there is a brief shot where Chazz is alone skating in the same storage where, much later in the movie, Jimmy and Chazz practice for the World Wintersport Championship.
Other mistake: The window in which Ben climbs in at Reverend Frank's house seems too narrow when viewed from the outside. But in the next shot inside the house, the window is wider.
Other mistake: When Chuck is driving Cam to get her spare set of keys you can see it is dark out and the car has its headlights on, but the taillights are out. (00:25:50)
Other mistake: Whenever the fire scene is going in slow motion, the fire in the background is not in slow motion. (01:07:00)
Other mistake: When Rod kisses Denise at the bus jump, Kevin is filming it, but it's apparent that the camcorder isn't switched on because the LCD is not lit up, it is just a black screen. (01:10:25)
Other mistake: At the beginning of the movie, a sniper is preparing to assassinate the Chinese Ambassador, who he has in the cross-hairs of his rifle. After the shot is fired, we see the sniper rappelling down the side of the building, which is at least 17-18 stories tall. When Jackie Chan jumps out of the building across the street, we see that he and the ambassador were on the bottom floor, far back from the window. There is no way the sniper, from that angle, would be able to see his target in his sights.
