The scene were the camera follows behind the charity collector was entirely ad-libbed with the actor pretending to speak to people as he passed to make sure no one stopped as it was all taken in one shot.
Director Aaron Weight features as one of the members of public.
The original draft of the film would all be set to take place in the town centre, however on the day of shooting the director Aaron Weight discussed it with the two lead actors and together they decided that it would be funnier if the man left the town centre but was still being followed by the charity collector.
