Can you help to identify 70s UK horror film, please?
 

Hi guys.

I wondered if you could help identify a horror film, please?

It was on TV in the UK in the late 70s. It was British, I think, and all I remember is that it involved people worshipping Satan and I think there was a pentagram on the floor inside an old house.

Not much to go on, I know, but the scariest part for me (being a child) was when someone walks down the staircase with a disfigured face. It frightened the living daylights out of me, and my parents had to console me by telling me it was just a mask.

It's a long shot, but hopefully some kind soul will be able to help. Thank you in advance!

Lol.
And I don't know what film it is, will try and look out for you.

Not sure if it completely fits everything you describe,but The Devil Rides out certainly had devil worship and a scenes with a pentagram on the floor.

Was it Mr Sardonicus?
