Hi!
It's just that it seems to me that at the beginning there was only existing "Star Wars". The book (written by Alan Dean Foster, NOT George Lucas - HE had the idea and wanted Foster to write it in a good style and his name is printed on it) was before the films. And the original second book was named "Skywalkers Rueckkehr"(Rueckkehr=Return), also written by Foster. That story has nothing to do with "The Empire Strikes Back", it's just Luke, Leia and Darthi (as far as I've read it now). All I want to say is that the story has expanded, by far not everything was thought at the beginning. And so it may be that Darth and Anakin were not everytime the same person.

I think in the book "Return of the Jedi" was mentioned that Owen was Obi-Wan's brother. In the new episodes it doesn't seem so. Owen lives on Tatooine and Obi-Wan didn't even know that planet in Ep.1.

I've seen the three originals again yesterday. Be serious: compared to those masterpieces the new "Episodes" (how I hate this name) are only silly shit.

By the way: in the german "MAD"-magazine it's named "Pepsidose 1" (Pepsican1) instead of "Episode 1" . There was a lot of merchandising with Pepsi, right?
