Cannot remember the name, but...

.. I am looking for the name of a movie that was set underground. On the back we see some pale guy; or maybe he had purple skin and white hair, I don't remember. Anyways, he seemed to be screaming. It stated in the text on the back that the movie was a hazard to the actors as the caves where it was shot were classified as risky due to cave-ins and stuff.

Hot damn I cannot remember the name of the movie!! Does anyone know what I am talking about?

could be "secret of the phantom caverns"

Yep, soounds like that film, aka "What Waits Below" (imdb: http://www.imdb.com/title/tt0088392/)

I'd love to see this again - not the best film in the world, but was a pleasant surprise on tv one lazy afternoon, many years ago. Does anyone have a copy?
