Production manager Lorraine Cox's car can be spotted throughout the film - look out for the gold/green Cleo Russell uses to hide in towards the end of the movie, the car is in the movie so much it nearly got a credit and the end of the film.
The shotgun Lee Hutcheon (Danny the Pincer) uses is held together with black tape. Lee snapped the gun in half while preparing for a scene.
A huge Blue crash mat is visible during the scene 'Danny the Pincer' gets over powered.
