If we're straying into televsion, I should mention the most Star Wars influenced cartoon of the early 80's.

A Revenge of the Jedi poster actually appeared in an episode. (Hey, it was 1982!) I can't help but think the post apocalyptic setting heavily influenced the creators of Adventure Time. Both shows blend magic and technology, and abound with weird mutated creatures.
I was much relieved when the world as we know it didn't end in 1994...
