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.

Churchill" are visible on the actual book under the dust cover. Also visible is the script from which the actor is reading, tucked inside the book and held by clips.

Revealing mistake: When Rachel and Adam first meet, their cars crash in the car park. In the shot where they both get out of their cars, you can see a dry patch of ground under Rachel's car, but the rest of the area is wet. Why would that space be dry, if Rachel just crashed and it isn't raining heavily at the time?
