Heh, Sounds like you have a few years on me Doc. I saw Return of The Jedi at the cinemas in Sydney when I was 5 or 6. All I really have vivd memories of is the partially completed Death Star and the Ewoks. But that was enough, I've been somewhat obsessed with it ever since.
And sci-fi in general, I love 50's-to late 70's Sci-fi pulp novels as well as Asimov, Clarke, Aldiss etc etc... Its so much fun reading that now and seeing what was predicted and what just never happened. Some of it is eerie.
