Character mistake: Jimmy is at work, feeling sick in the toilet. Two other employees are talking at the sinks. The man on the left is called Phil by his colleague at the beginning of the scene, but at the end of the scene, he calls him Simon.
Continuity mistake: When Jimmy is riding along the cliff, the GS Scooter has a fly screen on the handle bars. When he rides back to take the long run up before jumping off the cliff, the fly screen disappears only to re-appear a couple of seconds later.
Factual error: The station scene shows a Class 50 Locomotive which did not work from Victoria. Looks more like Paddington Station. Victoria is the main station for the Brighton line.
Factual error: Many extras in the background of the fight scene are wearing late 70's clothes.
Factual error: In the scene where Jimmy and Steph are outside the cafe following the fight, the police arrive and they both run away. A modern pedestrian crossing button can be seen.
