Doctor Blood's Coffin(1961)

We dare you to look into Doctor Blood's Coffin.

After being thrown out of medical school for ethical violations, Dr. Peter Blood returns home to a small Cornish village, where he sets up a research laboratory in a secluded cave. There, he attempts to revive the dead, using kidnapped humans -- who he views as unworthy of life -- for their body parts, specifically, their hearts.
