Factual error: I work for a television channel in 'daytime serial' production and I can assure you that no actor is going to secure a recurring speaking role in a soap opera unless a comprehensive insurance policy has been secured. (This applies to feature films, too.) This will inevitably involve a medical examination. I'm afraid Mr Dorsey's plans are going to become dreadfully unstuck the minute he drops his y-fronts in the doctor's surgery. (No, he can't find a compliant or bribeable doctor - the insurance company will always use their own people.).
Factual error: If we are to assume the film is in chronological order over the course of a single school year, then why does the football scene come after Christmas has occurred? High school football season ends well before the holiday season. (00:47:00)
Factual error: When Gary unscrews the top to the nozzle of the front tire of Karen's bike it automatically starts to make a loud hissing sound as if it's losing air rapidly. This wouldn't happen as although the tire would lose air over time it wouldn't make that loud hissing sound unless there was a rip or tear in the rubber. (00:21:35)
Factual error: When the substitute teacher is teaching the children about reproduction, the Playboy magazine is from September 1962, but the year is supposed to be 1961.
