The big difference in the edits is the scene with the arm on the floor in the cantina. There are several different versions. Haha. You may have heard about "the great flipper debate," which is where it came from. Ponda Baba (the walrus man) has flipper-like hands, but in the original, it's a hairy arm, like the wolf man might have. Doesn't make any sense. So Ady made a flipper hand to replace it, but didn't use it in the end. It was then determined that it should be Dr. Evasan's arm, but Ponda's (he is the one that screams, after all!). So, the final version is a cameo of Ady's arm, as photographed by his wife. Haha.

Oh, and the DVD-9 has a full trivia subtitle track added. I don't think the other versions do. It's a great insight into how Ady made everything and some of the decisions he made. It's funny at times, too.
