In 1828 Scotland, Edinburgh surgeon Dr. Knox does medical research on cadavers he buys from murderers Burke and Hare, without questioning the unethical procurement methods.
The murders raised public awareness of the need for bodies for medical research and contributed to the passing of the Anatomy Act 1832.
Dr. Geoffrey Mitchell:
We are students of Hippocrates, but some of us are hypocrites.
In his opening monologue, Dr. Knox Peter Cushing states the human body has 260 bones. It has 206.
The Dyaliscope logo in the main titles misspells the widescreen process as "Dylascope".
The "Continental version" of Flesh and the Fiends features "sexy scenes" not in the "UK version." (Both versions are included on Image Entertainment's DVD, along with an alternate title sequence for the alternate title of this film as Mania.)
