Writers Stewart Williams and Paul Hupfield were challenged to think of the dumbest and yet most commercial title possible for a film, Lesbian Vampire Killers was the answer. They then went away and wrote the script.
In 2003 when the script was first created, the writers, both MTV producers at the time, intended to make the film themselves as a 'straight to DVD' B-Movie. Paul Hupfield was set to direct, and Stewart Williams was due to play the part of Fletch.
The film's fictional village is called Cragwich in Norfolk, England. There is actually a village in Norfolk called Cranwich, situated on the edge of Thetford Forest.
James Corden said on the Late Late Show that if he could go back in time and not do something he would pick this movie to not do.
