One thing I found interesting that the author didn't seem to notice is that the text of the Star Wars opening crawl in the behind-the-scenes photo[1] is radically different from the version that saw release.
The crawl that we've all seen is only 4 sentences long: two in the first paragraph, then two 'paragraphs' of one multi-clause sentence each.
The crawl pictured in the tweet[1] is a much wordier mess, and may well be the original crawl Lucas showed to friends and executives before Brian de Palma edited the text down for him. It also features something similar to Dan Perri's semi-rejected logotype at the top (cut off unless you click in or view the image directly), the angled 'Star Wars' block logo most prominently seen on the original posters[2] for the film.

I personally also have a preference for the link to the original Twitter post. So thanks to the mods for the correction!
But all the credit goes to the person who posted the awesome thread on Twitter (@Foone). I only copied the link on HN.
