As you watch this film your thinking that this is just another psycho doctor movie where he's hell bent on proving his experiments are correct but then the film becomes a minor Frankenstein entry, complete with a resurrected corpse. Good location shooting in a small Welsh village add flavor to this story and good color in the type of film. You would also think that this is a film from Hammer studios, but it is not. Hazel Court is good as the nurse but veteran actor Kieron Moore who has worked in other science fiction films is pretty good also. This is one of the few times he's played the villain and not the hero that saves the day. This does have its share of blood and the overall mood of the film is effective in a grisly way. Future director Nicolas Roeg is one of the cameramen on the film. Horror film fans should check this eerie little film out.
