Revealing mistake: When Seymour stands on the zebra crossing to stop Wesley's van, the zebra crossing is obviously a prop as there are no zig-zag lines painted on the road.
Revealing mistake: In the final scene when Foggy is on the horse, it rears up when frightened by Foggy's bleeper, causing Clegg to jump out of the way. It's obvious that it is a stunt double playing Clegg, as he has a different hair style.
