Revealing mistake: Near the middle of the movie Samantha Mathis is walking across the high school campus. The name of the high school in the movie is "Hubert Humphrey High School, " but behind her, above the library door, a sign says "Saugus High School Library". Shows better in 4.3 aspect. (00:31:45)
Continuity mistake: When the guy in suspenders sneaks a cassette tape of Harry's show into the boombox, at the place where the students are dancing, the recording of Harry busting Deever is a completely different performance. You can tell because the word "Why" (from "W-w-why is that, Mr. Deever?") is much lower in pitch.
Continuity mistake: When Mazzilli is talking to the reporter in front of the school, he lights smoking firecrackers and throws them behind him. When we see him light the first one, it is at least three or four inches long when we see it in his hand, but much shorter an instant later when it hits the ground. This happens again with the next one too, but this time it's shorter when we first see it and slightly longer when it hits the ground. (00:54:25)STP
Continuity mistake: When Paige is shown brushing her hair in front of the mirror, there is no background shown in the mirror behind her; it's completely black. We see this a few times while she's sitting at the dressing table, but then when she gets up to gather her things and take them to the kitchen, we see the room reflected normally.

Factual error: Upon finding the cordless phone's base in the shed outside Mark's neighbor's house, the cop says, "There's the transmitter, which means the receiver could be in any house within 1,000 yards of here." I noticed no amplifier or anything to soup up the transmitter, and I know of no store-bought cordless phone with a range even remotely close to 1,000 yards. (01:09:05)Matty Blast
Audio problem: Just about every time someone starts or stops a cassette tape, we can see that they're either faking it or pressing the wrong button. In one shot, the 'Pause' button is down both before and after the actor presses 'Play,' which would of course mean that the tape shouldn't play at all.Matty Blast
Audio problem: Around half an hour into the film, some kids are listening to a tape of the radio show and a teacher takes the tape out because he doesn't like the content. As he takes the tape out, the audio ends right after the tape door opens, when it should have ended a little sooner, if it was actually coming from the tape player. (00:32:35)manthabeat
