Hi,I was wondering if anyone could tell me the title of a film that I watched when I was a kid in the eighties.The details are sketchy at best. I remember something about finding gold/treasure at the end of a rainbow, the people may have used it for transport. They also sacrificed themselves into a big hole surrounded by fictional characters for gold dust. That's about all I can remember, Please Help

I`ve not seen this one, but it sounds like a description of Great Land of the Small (http://www.imdb.com/title/tt0093116/).
