I remember being a small child and seeing this sort of scene on our television screen.

There was a giant pit with thick tar at the bottom. People were sliding down under the tar and some were never seen again but a small few came back out with fairy wings on their backs.

I don't think that I made this memory up, but I can't seem to find anything online. I've searched for years!

Please help!

Might be The Great Land of Small (http://www.imdb.com/title/tt0093116/)

I haven't heard this one offered yet! I'll look into it right now! <3
