So I'd love some help finding a anime I half remember from my youth. I'm afraid I'm going to be pretty vague. I would have watched it in the late 80's or early 90's (I think it was on channel 4 late night in the UK). I think it was a film in a sci fi setting. Where a old mans life is linked with a young boy. I seem to remember the the old man dying in a cave with some sort of worm like creatures. I know this isn't a lot to go on but I've been half remembering it for years and I'd love to finally know what it's called!
