The location recording for this production was a slightly strange one. The majority of the film has no in shot dialogue, relying on a voice over layered over predominantly atmospheric sounds and some breathing sounds. The segments on the tube were recorded using radio mics and a small handheld recorder in a discrete shoulder bag. Due to limitations to the number of crew we were allowed some crew simply had to travel on a travel card and remain relatively discreet while we were filming. The voiceover was also recorded by me at my home studio.
