Let Sleeping Corpses Lie (1974)
George and Edna are reluctant traveling companions that come across a small English village infested with the living dead. Seems that an experimental agricultural machine using radiation waves to make food grow larger has an even more interesting side effect when it starts to wake the now flesh hungry dead.
One of the better zombie films to come out of the 70’s, Jorge Grau’s horror classic is must viewing. Complete with interview with the director, TV and radio spots, and a poster and still gallery. Now out of print, so supplies are limited.
