Premiered at BAFTA in 2009 as part of the B3 Media 'Blank Slate' programme, supported by the UK Film Council.
For safety, two trained attack dogs were used to film scenes featuring 'Haydeez' the Rottweiler. Ultimately only one dog made the final cut, Harry.
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.
Director Mustapha Kseibati cast actor Paul Khanna in the role of 'Kevin' after seeing him in a self recorded home video audition. Months before the same actor had recorded another such audition, being cast by director David Yates in Harry Potter and the Deathly Hallows: Part 1 (2010).
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.
