An American Werewolf in London is a genre milestone and one of the few horror films that successfully manages to balance humour and suspense without mitigating the overall tone of the story. 40 years on from its theatrical release it still holds up well with its bitter sweet love story, tragic themes and ground breaking transformation effects by Rick Baker. Director John Landis never really bettered this concise and effective genre outing. It hits the mark in virtually every part of the production. However, there is one aspect of the film that does suffer as a result of the director’s personal choices. Whether it is to the detriment of the overall film is debatable. The point in question is the film’s soundtrack and the director’s focus upon the song Blue Moon by Richard Rodgers and Lorenz Hart.
