Well, pardon me for being excited at the prospect of watching Donald Pleasence and Peter Cushing in a '70s horror film. It does not take long to see why this film, titled "Land of the Minotaur" in the US but also possessing the horrendous title "The Devil's Men", is not more widely seen today or spoken about. It is such a dull film lacking in scares, drama and any other sort of talent that it is a wonder that Cushing and Pleasence were even in it. It has to have been a good pay-day for them. In fact, the entire budget must have went towards securing their contracts, because evidently there was nothing else left by the time they went to shoot this absolute borefest. Nothing happens, and there is nothing of interest apart from the banter between the priest and the PI, that swings between jovial and nasty. The director must have slept his way through the film, the editor had nothing to do because the film gives the impression that what was shot as quickly as possible and stuck together. Every single trope you can think of from Satantic horror films makes its way in here, and is done in a way that the film-makers shrugged and said "They've seen it before, why bother making an effort or putting a new spin on it?"
I am surprised of Cushing and Pleasence not being able to see through this one when they were approached.
