OK, so there were more instances of "Return" being mentioned. I still don't buy the "Revenge = fake title" story, especially because zombie quotes the findings of a market research study conducted by LFL at the end of 1982. The footnote citation says it comes from Steve Sansweet's "Star Wars Vault" book, a Lucas-approved publication.

I find it very hard to believe that they'd have conducted a study on reactions to "Revenge" vs. "Return" if "Revenge" was a bogus title and they were intending to call it "Return" the whole time. It's just more of this whole "everything was planned out"/"Lucas is infallible" bullhonky.

It would have been much more honest to admit that during production and up until the end of '82, "Revenge" was the decided-upon title, and that it was changed to "Return" because Lucas decided that a Jedi wouldn't take revenge (i.e., he changed his mind) and/or the fans didn't like the idea of Jedi seeking revenge (i.e., Lucas realized that calling the film "Revenge" was a mistake). Of course, we're supposed to believe that George Lucas doesn't change his mind or make mistakes, hence "Return was always the real title and Revenge was a fake title".
