I know this is a wide range but the movie is 70s-80s. It seems like it was aired on the sci Fi channel. The only thing I remember is a woman was chained in a cave and some sort of monster came in to rape her I think. That’s all I remember because I had to catch the school bus..
The Dungeonmaster (1984)?
I’ll have to find it and watch it to know for sure. I see the full movie isn’t available on YouTube. I appreciate your feedback
The original ‘Clash of the Titans’ has s couple of scenes with a woman chained up and a monster coming to get her.
