The Black Sleep
The Terror Drug That Wakes the Dead!
Directed by Reginald Le Borg
Produced by Bel-Air Productions, United Artists
A Gothic mad-scientist horror film that uses suspended animation and brain experimentation as a vehicle for exploring bodily horror and moral transgression in a decaying English abbey.
In 19th century England, a noted brain surgeon rescues a former student from being hanged on a false conviction for murder, and spirits him away to an ancient, repurposed abbey far in the countryside. There, he connives his pupil into assisting him in mapping the functions of the various parts of the human brain, using living subjects who are under a terrible animation-suspending drug called "black sleep". Subsequently, the student, along with the daughter of one of the subjects, discover that most of these subjects have survived but are being kept in a dungeon-like cellar, in various stages of physical and mental derangement...
