Actor(s):  Cristina Galbó, Ray Lovelock, Arthur Kennedy, Aldo Massasso

Brief Description  Let Sleeping Corpses Lie (1974), also famously known as The Living Dead at Manchester Morgue, is a landmark Spanish-Italian eco-horror zombie film directed by Jorge Grau. Set in the lush, rural English countryside, it stands as one of the most uniquely atmospheric and influential European horror films of the 1970s, notable for introducing ecological themes and visceral special effects to the evolving zombie subgenre.

Plot:
George Meaning (Ray Lovelock), an cynical antiques dealer from London, is traveling to the Lake District when his motorcycle is accidentally backed into and damaged by Edna Simmonds (Cristina Galbó) at a gas station. Stranded, George insists that Edna drive him to his destination. Along the way, they lose their bearings and encounter local government agricultural workers testing an experimental pest-control machine. This device utilizes ultrasonic radiation to target and destroy the nervous systems of crop-destroying insects. Unintentionally, the high-frequency radiation "jump-starts" the nervous systems of recently deceased humans, reanimating them with a predatory craving for human flesh.

Edna's troubled sister, Katie, is staying nearby in a secluded cottage. While Katie is isolated, a local vagrant named Guthrie—who had recently drowned—rises from the dead and brutally murders Katie's husband, Martin. When the local police, led by a fiercely conservative, authoritarian Inspector (Arthur Kennedy), investigate the killing, they reject the bizarre tales of walking corpses. Instead, the aggressive Inspector targets George and Edna, pinning the "Manson family-style" murder on the two young, long-haired outsiders.

As George and Edna desperately try to clear their names and track down the truth, the ultrasonic machine continues to operate, reanimating more bodies in the local graveyard and a nearby hospital morgue. The small number of zombies are highly aggressive, possessing the ability to smear victim blood on other corpses to wake them up. The film culminates in a claustrophobic siege inside a hospital where the outbreak spins out of control. Despite George's attempts to destroy the dead and deactivate the machine, structural tragedy strikes due to the Inspector's stubborn incompetence, culminating in a dark, ironic twist of fate.
