Yes, we have the DTS discs. No they do not have the “to be angry…” scene.
I have no knowledge of how the audio was presented/processed in the DLP presentations of that time. They might have used the DTS discs, or possibly some other method.
They just brought in a giant HD with all the video and audio files and the video back then was not lossy compression either, 100% lossless (well, certainly for TPM, maybe it had changed by AOTC, but probably not)
I might have thought the to be angry was there in the DCP, but no good memory to be sure at all, could super easily be totally wrong. I wonder if I have any notes anywhere from back then.
I also got to see the DCP for TPM at two different theaters, each used a different projector type.
One of them was played at one of the original smaller twins that used to pair with one of the mammoth screens that showed Star Wars on opening day in 1977 in 70mm (since split into 8 screens!!! 4 upstairs and 4 down!) that got one of the initial 70mm print runs before the 70mm prints got a bit changed for the later 70mm release. Oh man was that something. Going from having just seen some movies on a tiny mostly mono, maybe weak stereo 35mm mall screens to a giant screen with 70mm and surround sound and that Star Destroy just coming down the screen for ages at the start! Also saw ESB in 70mm there too. Man those were something. (I am among those crazy few who could swear we saw Luke miss his first toss in the Death Star and recall the scene being longer and more suspenseful and the door took longer to prop up in that initial first 70mm showing. If it somehow truly never happened, it is weird how we all came up with that independently. I had that in notes I wrote down as a little kid back in later summer '77, long before I had ever met anyone else, beyond my parents, who had ever seen it in 70mm on opening day. How did any of us come up with that?
One for sure beyond sure thing is the whole “close the blast doors! close the blast doors!” “open the blast doors! open the blast doors!” thing which later got removed and then mangled and not sure any home release has ever had the full length sequence of that as it was originally.)
