Monthly Film Bulletin wrote: "This preposterous mixture of crime, horror and science fiction, with a dash or two of neurosis, art and medical ethics stirred in, comes off unexpectedly well. With some notable photography credits to his record, director Freddie Francis not surprisingly has an eye for the startling or sinister image: the shadowy airport, the wild-eyed portrait of the telepathic tycoon, the brain dying in a swirl of chemicals. Once past the turgid dialogue of the opening scenes in the laboratory, direction, script and editing keep things roaring along with piled-on complications confusing the trails, and a neat pay-off. A strong cast gives momentary credibility to the hocus-pocus, with
Jeremy Spenser enjoyable as a repulsive father-hater. But pointless miplausibilities in the story – brain-baths apart – will jar on the observant spectator. And it's a bit much having apparently two alcoholics in one picture."
The Radio Times Guide to Films gave the film 3/5 stars, writing: "
Hammer Horror veteran Freddie Francis does a decent job directing this version of
Curt Siodmak's ''
Donovan's Brain''. Peter Van Eyck is the scientist controlled by the power-crazed organ of a sadistic tycoon kept alive after a plane crash. More of a mystery than an all-stops-out horror, the moody tale has some eerie moments and is efficiently involving. A competent cast injects new life into a familiar story."
Leslie Halliwell said: "Twisty remake of ''
Donovan's Brain'' [1953], not too badly done." ==See also==
