Audio problem: In the scene where Todd and Jeremy are in the bedroom together and Todd is lying on top of Jeremy asking to play "tummysticks", - right before Sen Clary is about to come in and Jeremy begins to panic, watch Jeremy as he's lying on the bed talking. You hear him say about three sentences, but see his mouth move for about one from the left side view of his mouth.
Continuity mistake: During the football game where Jeremy & Zack "tackle" for the second time, Gloria and Mrs. Cleary are startled and jump up from their seats. In one shot Mrs. Cleary's glass is filled about half way with a redish liquor, but in the next it is a hardly visible clear liquid.
Factual error: Without getting into the physics of the whole thing, there is no way a shotgun, and especially a shotgun with the kind of shells they were using, could knock a full grown man down like that. At worst he would be bruised from the re-coil, or the weapon would fly out of his hand, depending on how he was holding it at the time he fired.
