The Devil's Men. A Satanic cult led by horror legend Peter Cushing are committing human sacrifice to a Minotaur figure in rural Greece and it's down to priest Donald Pleasence (another horror legend) and his friend from New York to put an end to it.
I've read mainly negatives about this movie and it certainly has flaws. For a start Cushing looked to me like he was merely going through the motions. Pleasence played an Irish man but his accent kept slipping. Having an interest in the occult I felt that there was a lack of information about the cult, it's beliefs, origins, etc. And the finale was rather sill, but entertaining. However, on the positive side it is visually very good, plenty of colour and great use of Greek locations. The musical score, by Brian Eno, is effectively menacing. Some reviewers found it boring but I did not. Being a 1970's Euro horror movie we get some nudity, plus a fair amount of blood and gore. It's really not too bad.
