I'm not sure if what this guy says is true about the file he acquired (or if he just created it himself) but this scene looks awesome in HD. I'd get the BD if this is the quality we are looking at.
This video has come up before, but where do you see any claims that he acquired the file from an official source?
I saw it in one of the comments. That's where I got it from so that's why I wasn't sure.
