I saw the film tonight, screened from the RAH. The experts have done a brilliant job with it. The whole film has been left untouched as regards characters, script etc. (Including the "N" word, which has resulted in a higher classification apparently.) What they have done is clean everything up, almost frame-by-frame, so it's up to modern standards. Being able to see it like that, and on a big screen, was excellent. I believe this version will be available soon, and the presentation tonight by Dan Snow is supposedly available as a free download. if I find the link tomorrow I'll post it.
And yes, it's now high definition emotion, but still the same feelings in the gut.
