I was there.

1. From what I've read, it was actually the 1981 re-release print, as it had "EPISODE IV - A NEW HOPE" and "Close the blast doors! Close the blast doors!" was missing.

2. The print is in really, really, really great condition. The Star Destroyer in the opening looked a little pink, which I'm guessing was a tint affecting the whole film, and there was some dirt when Owen was buying the droids (I think...it was on Tatooine, I remember that). But other than that? Amazing. It was beautiful.

3. Seeing Star Wars with an enthusiastic crowd that laughs and cheers and claps throughout is a lot of fun. Also fun is the mixed reactions to Leia kissing Luke on the cheek. "Yeaaaah!" and "....uuuuuh....."

4. The print is owned by a private collector in Britain. The Senator had been run by the same family for 71 years, so they had a lot of connections. Thus, when word got out that they were closing, friends talked to friends talked to friends and got them the print to use.

P.S. The Senator will reopen under new management...soon, hopefully. Gorgeous theatre.
