I saw this movie back when I was a kid in the 1980’s. All I can remember about it was there was a stair case that lead to a basement. And there was a hole or well in the floor that had a green glow to it. It was like it was a gateway to another world. I remember a guy falling into it, buy that’s all I can remember, I sure hope someone can help me with this, cause I’ve been all over the web and even YouTube, and I keep coming up empty handed. TIA!!
Amityville 3-D (1983)?
The Gate (1987) ?
Don’t Be Afraid of the Dark (1973)?
