The character of crazed drug dealer 'Kevin' was based on a real person who auditioned to play themselves in the film. Director Mustapha Kseibati eventually cast actor Paul Khanna for the role, declaring he was 'more Kevin than Kevin' after seeing a home audition clip.
The film was originally entitled "Knife", a story about a group of kids who end up going on a failed robbery. After writer and director Mustapha Kseibati showed an early draft to Tom Shankland, he was inspired to change the story emphasis to comedy, a genre more appealing to a generation frustrated by darker drama.
Actors Tobi Akinboboye and Marcus Boyea were not meant to be considered as the characters they ended up playing were scripted as 17 and 18 years old respectively. An administrative mistake got them to audition whereby they impressed director Mustapha Kseibati and producer Michael Berliner and won their roles.
The film's soundtrack was largely provided by Manchester MC Envy. Mustapha Kseibati had previously directed two music videos for her including "Tongue Twister" and "Friday Night" for Stop Start Records.
The film was shot in Hounslow, a town that sits directly on a Heathrow Airport flight path. As a result, takes had to be scheduled to fit in precise 80 second gaps where air traffic noise was low enough to not interfere. The ensuing technical and artistic pressures were considerable on cast and crew alike.
