I just love your site, and am getting lots of good tips on movies to see. Also, it helped me to revisit a horror that terrified me for years after watching it at the tender age of 14, it was PIECES. It truly made me feel sick for a very long time. I hired it again when I was about 23, but just couldn't bring myself to watch it; the memories of the horror were too strong. I am happy to say that after discovering your site and seeing a clip on your youtube page, that at the more mature age of 39 I was able to sit through the whole movie, and even giggle a little. Yay!!! The power has been taken away from that particular nastie.
My find-that-film has been bugging me for at least 15 even 20 years. I watched it when I was very young, maybe 8 years old. I was born in 1970 and the movie was probably from the ‘60s or ‘70s. A HAMMER horror type (don't think it is though) with a male actor, PETER CUSHING type (probably not him though). The only scene I remember which I think was near end of movie…. a woman tied up and possibly gagged lying on an alter/bed type thing, in a church(?), under a white sheet. Next to her a man with a knife, looking all possessed about to plunge knife into the woman for a sacrifice; woman squirming away from position of knife raised above her, then suddenly another man bursts in and shoots the knife wielding man in the back. The woman was a real woman (not a child), naked but covered by a white sheet. She is on the bed/alter and fully aware of the pending sacrifice, but not willing, there is fear in her eyes and you can see her move her body under the sheet trying to get away from the knife, which the man is holding above her. You can see she wants to escape and thinking by moving her body she will avoid the plunge of the knife, this is why I think she is tied and gagged, not a mesmerized victim as you often find in these types of movies. Anyway, someone bursts into the room/church and shoots the villain in the back. End of movie.
Hope you can help. Glad to get the nightmare of PIECES out of my system, now just to figure out this little bugger….
