Alternate Versions

The version broadcast on the BBC (22.09.01) is uncensored and thus different to the cut version that played British cinemas (in 1971) and the identical Derann tape release that appeared in 1981.
  • The opening murder in the BBC version includes a more prolonged strangulation scene, as well as some further nudity as Kenny strips his dead victim (Janette Wild). There's also the sight of him removing a watch and necklace from the naked corpse, adding a (slightly out of place) petty criminal element to Kenny's religiously motivated crimes.
  • The title scenes are slightly different, the BBC version plays the title over a still shot of the killer's boots (the rest of the credits appear the same way). The Derann version plays the title over a blue box background.
  • When Kenny first plays the audio tapes back of his killings there is some cutaways to historical torture paintings. The older Derann version includes two brief shots of the same painting, the BBC version contains the same two shots but lingers on them a little longer and goes on to another shot of a second (more graphic) painting.
  • The murder of the prostitute (Terry Quinlan) in toned down in the Derann version (she's beaten around the head off-screen). The BBC version however includes some nasty shots of Kenny ramming his torch into the girl's mouth. Her death from being beaten around the head is no longer shown totally off-screen in the BBC version either.
  • The following scene where Quinlan's body is discovered in cement, is different in the two versions. The BBC version represents this scene with two shots of nudity (the actress obviously found it hard to hold her breath). The Derann version represents it with an odd, (still photograph?) close-up on the girl's face.
  • The last difference is to the 'meat-hook scene' where one of Kenny's victims (Suzanna East) initially drowned is discovered hanging on a meat hook. Both versions play the discovery slightly different, the Derann version includes a brief shot of the girl on the meat hook as well as a second shot that zooms in on the dead girls face. The BBC version begins with an additional long shot of the dead girl, and ends on a second shot, that's actually the first shot we see of the body in the Derann version but is more drawn out. The zoom shot from the Derann version isn't included in the BBC version.

Ultra low-budget non-horror silly propaganda piece
11 February 2007 | by HardylaneSee all my reviews

A truly dreadful film, seen during the night on BBC2, but glad I saw it! A fairly comprehensive anti-religion film... anyone who comes into contact with it becomes maniacs! Superb! Notable for yet another Patrick Magee scenery-chewing exercise, a host of unknown actors who remained unknown, and a truly jaw dropping series of appalling songs, sung by the "Shirley Bassey" Stars in their Eyes winner, Maxine Barrie (in her younger days!). Poor dear had to wait over 20 years for public recognition. If I were her, I'd buy all the prints and burn them! Definitely a B-movie for showing in a double bill with some cheapo Hammer concoction, but unintentionally funny in places.
