I'm really lucky with this one, because it was on TV when i was little, and my mum decided to record it, so I now have a VHS copy of it.
It's actually the best version of Stevenson's book that I've seen - lauded as staying very true to the original storyline, which it does, so in that respect at least it's superior to the other versions, as they felt they had to change the storyline +/ characters to make a good film.
I also liked Treasure Planet, but i hated the muppet Treasure Island and the Disney live action one :3
