The cemetery scenes in the film were shot at the historical English graveyard where Robin Hood's Little John is said to have been laid to rest. The production experienced trouble though when tourists arrived to see the crew (and their garbage) hanging around the cemetery. Complaints were made and the film crew was forced to wrap shots in the cemetery in 24 hours. See more »

Now THIS is a zombie movie!
15 July 2005 | by (Beverley Hills, England) – See all my reviews

I've been a fan of zombie films for pretty much the same amount of time that I've been a fan of films, and I thought I'd seen just about all there is to see from the horror sub-genre. So you can imagine my surprise then when I came across this hidden gem! Let Sleeping Corpses Lie does everything that you would want a zombie film to do; it has gore, shocks, atmosphere, humour, intrigue and a typically thin plot line, which allows the film to put more emphasis on the more important aspects, rather than swamping itself in needless plot details. Of course, the film does somewhat cash in on the success of George Romero's zombie milestone; 'Night of the Living Dead', but really; it's almost impossible for a post-Night zombie film to not have that comment lauded upon it, and Let Sleeping Corpses Lie has enough about it to more than adequately rise above the Night of the Living Dead rip-off's. The classically styled zombie film story follows a group of farmers that create a machine to kill insects with ultra violet rays. However, this contraption does more than it says on the tin, as recently deceased members of the public start popping up, just around the same time that George and Edna; two people that came together after an accident, roll into town.

Ray Lovelock takes the title role, and looks the part as a young London man. His style, along with very over the top dubbed in London accent work a treat, and his performance adds something of a sense of humour to the picture. Christina Galbó has less to do opposite Lovelock, but she does well with what she has and makes for a good heroine. The film starts off rather slowly, but the relaxed pace never makes the film boring, but it does add to the film when the horror really starts; as we're sufficiently on the edge of our seats by then. Director Jorge Grau creates a fabulous atmosphere through his English countryside setting, and I personally thought it made a very nice change for the zombie antics to be set in the English countryside rather than America, as they usually are. Despite the fact that this is an Italian film, the filmmakers have managed to implement a great British feel to the movie, and the movie feels something like a fusion between Italian and Hammer horror. This is certainly a plot line that Hammer would have taken on! The gore in the film is few and far between, but when it's on screen, you'll definitely know about it, as it doesn't exactly hold back! On the whole, I think it's criminal that this film hasn't won itself more recognition. Let Sleeping Corpses Lie is a film that I wont hesitate to name as one of the best zombie films ever made, and it therefore comes with the highest recommendation!
