Other mistake: When Sam is texting Austin, she gets the reply the split second after she sends her text. There isn't enough time for Austin to read the text and reply.
Other mistake: Vivian and Bernard are standing outside of Albert's Open Spaces office taking to him when Tommy calls Bernard's cell phone. Bernard hands the phone to Vivian, who takes the phone and puts it next to her ear, upside-down, and begins talking to Tommy, through the speaker, and listening to him, through the microphone.
Other mistake: During the opening sequence, walk of fame parody, Lawrence Fishburne's star appears twice above Seal's star. (00:02:55)
Other mistake: Towards the beginning of the film when Oz talks to Jill on his cell phone in the car and he hangs up, you hear Jill answer Jimmy in Oz's cell phone. (00:13:25)
Other mistake: After the funeral, the guys visit the clubhouse. They open the box for DB Cooper's treasure. The blood they used to sign their blood oath is too red to have been 20 year old blood. It should have darkened to deep, deep purple or brown by now. (00:12:40)
Other mistake: When Ms Norbury passes back the failing grade on the math tests and states she needs it signed by her parents, the test states it's the "Limits Test" but the test is on convergence and divergence of infinite series.
Other mistake: At the very end, when a man is painting the "F" of the city's new name on the water tower, with white paint, you can see that though the brush is white, and it is touching the surface of the water tower, no paint is left on the surface of the water tower. Nevertheless, the painter continues painting the letter in the next shot, even though no paint is left on the surface. (01:36:00)
Other mistake: In the end when everyone is on the Kippie Kann show, they show the clip of Lulu and Joyce at the restaurant. It shows Lulu saying, "I'd say it's nice to see you, but then I'd be lying." In the restaurant scene, Lulu never says that.
Other mistake: On the first day of the Big Bounce, during the dancing, a white towel-like object is dropped on the floor and in the next shot it is gone.
Other mistake: The scenes that are supposedly located in St. Bart's have Chinaman's Hat in the background, which is a distinctive Hawaiian landmark.
Other mistake: When Abigail keys in her password to the preservation room, she only presses the keyboard 9 times including the return key. If "Valley Forge" was the password, she would have had to have used at least 12 keystrokes (including the return key.) And she never goes near the "L". (00:33:20)
Other mistake: When the gang are watching the news report in their van, Heather Jasper-Howe shows the clip of Fred saying "I think Coolsville sucks" - problem is that there was not enough time for the crew to edit Fred's short interview and be able to transmit it that quick. (00:37:00)
Other mistake: Just before the second period against the USSR, we see a couple of shots of the benched Soviet starting goaltender Vladislav Tretiak. His hair is dry and combed, and there is no sign of perspiration, despite having just played the whole first period. After the game is over, we see a shot of the Soviet players watching the Americans celebrate. This time Tretiak's hair is wet and his face is sweaty. Shouldn't it be the other way around (i.e., hair is wet after playing one period, then dry after sitting on the bench for two periods)?
Other mistake: When Paul is making the DVD, there's a record of Terri performing a song she wrote(One more mile to Jericho). At the very end, outside the school the kids start play some music together with Terri singing. That's supposed to be some random thing like it was before, but actually they play and sing Terri's own song. How come?
Other mistake: Wendy loses her accent and it changes at points, such as when she asks Matt if he's hungry.
Other mistake: When James Gandolfini hits Ben Affleck over the head with the shovel for burning something in his front yard, he falls, but his head never hits the ground. You can actually see Ben Affleck holding his head up a few inches off the ground. An impossible feat for someone who is supposed to be unconscious.
Other mistake: When Jack is reading the paper about the death of two other characters in a hotel, there's a newspaper insert and we can see that, with the exception of the headlines, everything is mumble-jumble, incoherent text just to fill the space.
Other mistake: When Jordan Cahill sings on the porch of the old house, he is holding the guitar but he is not actually playing it (he's not really fingering on the fingerboard).
Other mistake: In the opening scene where the two cars race. they use a traffic signal to start the race. This traffic signal is in the middle of nowhere and there is no intersection at this light and a single lane road. Also, there aren't even supports for the traffic light on either side (which would be necessary because the light is suspended from a wire), which is most visible during the crane shots.
Other mistake: The morning after the creatures give warning, the camera pans across the village. To the right, just left of the school, is the house where Lucius is put after he is stabbed. Notice the two smaller windows to the right of the door. Fast forward to the last scene, Noah's parents are sitting on the left and behind them you get to see the window frames are larger than the windows seen from outside. My guess is that the windows were bricked up so there would be better lighting for that scene.
