I don’t have much to go on except this one scene. I believe the man is being chased by cops. The “slide” is enclosed by a fence and one of the cops is telling him not to go down cause of whats down there. Monsters of some sort are at the bottom.
I saw this when I was a kid and have tried to find it for many years. It was in English and I might have seen it on tv, I just don’t remember.
When I first tried finding this movie everyone kept telling me it was Running Man with Arnold, but thats not it.
