Going through the changes as I have all of the caps done.

Question: The "EPISODE IV" title was added in 1981. But when did all of the reformatting happen so that they capitalized "Rebel" and so forth? The "official" comparison text says 1979. How many crawls are there?

Yeah, I noticed that, it's a little weird but if I understand it correctly, Episode IV appeared on the revised script in '79 so maybe that's what they mean or maybe the '81 opening crawl was created already in '79 but not spliced in to the actual film until '81.
