Hey all. I'm trying to find the title of a children's movie. I don't know how old it is, but certainly no later than the early-mid 80s. Problem is, I remember only one scene and that looked like maybe late 70s early 80s?

It was fantasy I think, not animated. I don't remember the language though or whether it was subtitled.

The scene is of a young, small blond(?) girl (around 10-12 years old?) who sits hunched or is bent over next to the wall of a cave(?). Her expression was kind of sad and attentive. She is listening to a voice coming out of a crevasse in the wall. There was also light shining in this crevasse. You don't see who/what's in there, but I think the voice was of something/someone trapped asking for her help. She might have had a pendant or a necklace? Not sure. Might be that there were other pple with her in the cave, but not many in any case.

I was really young when I saw that and I don't know anything else about the movie. I've looked through this thread up to page 7 and I found something that might be it but unless someone recognizes this scene I can't be sure.

Bro and sis search for crystal and long-lost father (https://www.askmehelpdesk.com/advice/t-278705.html) : this is the other thread.

I know it's a shot in the dark but if anyone remembers I'd be very happy. I've been looking for this title for two years.

Thanks in advance.

Does anyone have any idea? It is not a scene from Into the Labyrinth. I've also watched Crystalstone (1988), the movie Quinn suggested, but it's not that either. It might also be from a TV series.
