Corrected entry: In the scene where Bender escapes from the closet, he is shown crawling above a drop-ceiling, eventually falling through. Bender shouldn't have been able to crawl as far as he did because a drop-ceiling would never support his weight.
Corrected entry: How does John Bender get back up into the ceiling from the library?
Correction: He could easily have gone up to the top floor of the library and piled up a couple of tables. The ceiling isn't that much higher than the top floor, and he is seen to be quite a good climber.
Corrected entry: In the scene where John, Brian and Claire are talking about virgins, the last shot of Brian you can hear dogs barking in the background.
Correction: Fair enough but it isn't really a mistake-there could well have been dogs barking outside the school.
How could a dog be heard when they're deep inside the school? The principal can't hear them outside the library, but we can hear a dog hundreds of feet away.
Corrected entry: At the beginning of the movie, Brian reads the beginning of his essay/letter to Vernon. It reads like this: Dear Mr. Vernon, we accept the fact that we had to sacrifice a whole Saturday in detention for whatever it was we did wrong. But we think you're crazy to make us write an essay telling you who we think we are. What do you care? You see us as you want to see us. In the simplest terms, in the most convenient definitions. But what we found out is that each one of us is a brain. The question, "What do you care?", disappears at the end of the movie when he reads it again, yet it's supposed to be the same essay he writes at the end of day.
Correction: There are actually a lot more differences in the two versions of the essay than just that. It's definitely intentional and purposeful that he is not saying the same thing and not a continuity error.
Corrected entry: Why is there a piece of wood covering the front of the table that Molly and Emilio were sitting at but there aren't pieces covering the fronts of the tables that the other kids are sitting at? I know that Judd Nelson hides underneath the table later on in the movie, but still, it looks like a piece of wood was just attached to the front of the table at the last minute or something---it doesn't look natural.
Correction: There's nothing wrong with having a piece of wood on the front of a table. Nothing says there can't be.
Corrected entry: The school is supposed to be in Shermer, Illinois 60062, but a Georgia flag (1956-2001) with the confederate symbol is shown in the library. (00:57:14 - 00:57:40)
Correction: The library is shown to have several State flags hanging throughout, not just Georgia's flag.
Correction: Not true. If he was careful to maintain his weight on the support struts, and carefully distributed across his feet and hands, many drop ceilings would support his weight readily. It was putting all his weight onto one of the tiles that was the kiss of death.
