I know this movie was on tv in the 80s in English I don’t remember much but I do remember thinking it was about a child and I think his parents were killed. I think it was a car accident or actually possibly was a spacecraft crash I believe it’s possible it took place in the future and then I remember there being something about a giant and a dark cave or possibly even a suspended cage in the air in his cave.
Time Bandits – has a giant, suspended cage in darkness, a giant, and a lot more!
Oops – mentioned giant twice – meant to say parents killed…
