I saw this on a cable movie channel late at night sometime in the 90s. I remember very little, but there was a young male and young female character (probably 20s) who entered another dimension – I think through a mirror. I seem to remember them falling in this other dimension and it was pitch black. They were separated from each other and yelled out. I don’t remember if they heard each other. I *think* there was some sort of time device as well, maybe controlling the entrance to this other dimension?
One other memory that I think is from the same movie – but I’m not entirely certain – is some sort of dungeon scene in which a woman is being sacrificed on an alter. I think there were chains involved, and I believe she was naked. I believe this took place before the two characters ended up in this other dimension, but, like I said, I’m not even 100% sure it was the same movie.
Waxwork II:Lost in Time(1992)?
I’m not positive, but it looks promising! I’ll have to check it out!
