Other mistake: When the Aggies are in the locker room after the football game, they are all getting undressed and showering. This is happening right after the game yet none of them have a spot of dirt on their nice white uniform pants. (00:59:50)
Continuity mistake: In the scene where Victoria is watching man eat a cream cake, the man has cream on his nose but in a different shot he has none.
