The title has more punch than the story ultimately delivers in this mild shocker, yet another variation on the old "Frankenstein" theme. Kieron Moore ("Crack in the World") stars as Dr. Peter Blood, an intense scientist determined that his experiments in extending life will be successful. Unfortunately for him, he's not very good at what he does, either getting caught in the act or leaving critical evidence in his wake.
"Doctor Blood's Coffin" is mainly noteworthy as one of the horror pictures made in England by under-rated, Canadian-born filmmaker Sidney J. Furie before he hit his stride with "The Ipcress File". The story & screenplay are the work of Nathan Juran (credited as Jerry Juran), himself a famed director of such things as "20 Million Miles to Earth". But, alas, this yarn is lacking in truly interesting features, although the tunnel settings are somewhat unusual. (Said underground tunnels, originally used as tin mines, run throughout much of the locations.)
These locations are quite picturesque, and the film does look lovely in colour, although one can't help but think that it would have had even more atmosphere had it been filmed in black & white.
The picture also offers its audience an opportunity to watch gorgeous Brit scream queen Hazel Court in a contemporary-set tale, unlike the period pieces from the 50s and 60s for which one might already know her. She's quite a formidable leading lady, obliged to scream at one point, but indignant enough that she and Moore pontificate back and forth on what constitutes the "right" thing to do. The excellent supporting cast also includes Ian Hunter as Dr. Blood Sr., Kenneth J. Warren as the police sergeant faced with baffling deaths, the colourful Gerald Lawson as local funeral director Mr. Morton, Fred Johnson as amiable miner Tregaye, and Andy Alston as one of our demented antagonists' intended victims. You have to give this guy credit for his extended, arduous escape.
Overall, this is short on suspense and originality, and spends too much time with Moore as he aggressively pursues Court (not that you can blame him, of course); this doesn't stay on track all that well.
