Let Sleeping Corpses Lie (1975)
A couple (Ray Lovelock and Cristina Galbo) travelling along the English countryside stop to get directions from a pair of Ministry of Agriculture workers who are testing an experimental device designed to drive crop-damaging insects into killing each other. While they plan their next stop, a man who has been dead for several days attacks--to be followed shortly thereafter by a full-scale zombie invasion--which could very well be a result of the agriculturist's distribution of ultrasonic radiation. A macabre, atmospheric Spanish-Italian co-production featuring extremely convincing performances and a haunting score by Giuliano Sorgini. The second half of the film contains enough gut-munching gore scenes to satisfy most horror fans, leading to an unexpected and eerie finale.
Two traveling companions, George (Ray Lovelock of AUTOPSY) and Edna (Christine Galbo of THE KILLER MUST KILL AGAIN), come across a small town infested with the living dead that are satisfying their cannibalistic hunger on anyone they come across. Discovering that an agricultural machine using radiation waves is at the root of all the havoc, George and Edna fight for survival and their innocence as they are pursued by a relentless detective (Arthur Kennedy of THE ANTICHRIST and FANTASTIC VOYAGE) who is convinced they are responsible for the ghoulish acts of violence plaguing the countryside. All this leads to a gruesome showdown at the Manchester Morgue an ending that knots a horrifying twist in the lives of all involved!Also know as THE LIVING DEAD AT THE MANCHESTER MORGUE and DONT OPEN THE WINDOW, this carefully constructed and beautifully photographed tale of the undead roaming the English countryside comes from acclaimed Spanish Director Jorge Grau.
