This has been driving me nuts for a few years now. When I was a small kid, I saw a movie that freaked me out, and I can't figure out what it was. Here's what I remember: It came out in the late 70's/very early 80's, and I probably saw it on HBO at that time It was about some people who got trapped in a house/castle by demonic forces They tried to cut the front door open with a radial saw, and someone's hand ended up getting caught in the blade There was a trap door in the basement that led to hell, and they meet the devil, who was either played by the guy who played Boss Hog, or someone who looked a lot like him. It scared the hell out of me as a 5/6 year old, but I'd probably think it's really campy if I saw it today. Any ideas?
