Let Sleeping Corpses Lie (1974)

Beardo biker Ray Lovelock is taking his Bee Gees hair out for some air when he has a little mishap with hippie Cristina Galbó and ends up having to finish his ride through the countryside in her car. Thus begins Let Sleeping Corpses Lie (1974), one of the earliest of the ample zombie romps that rose to conquer screens after the success of Night of the Living Dead (1968)—and, just as with that film, this flesh-chomping flick has a few sociopolitical bones to pick. Seems that people on the outskirts of Manchester have been messing with Mother Nature, and the bitch has returned the favor by siccing the undead on humanity's scrumptious head. The corpse of a recently drowned vagabond is the first to rise up and screw with the living . . . and Cris is a witness! But cop Arthur Kennedy doesn't much like longhairs, and he thinks Cris's junkie sis is the murderer. Abandoned by the Big Bad Establishment, Ray and Cris set out to stop the zombies on their own.
