For some reason i cannot access any of these “leaks”, pictures or the videos, but i did what the eckharts ladder video where he was talking about the leaks he had seen and showed some of the screen captures. Although the colouring was slightly different, i resized the screencap to the 2020 bluray and , apart from cropping, they overlay perfectly. If they were indeed a new scan of the theatrical then this would be impossible. Even a new scan of the SE negative would throw up differences. So , if he did see leaked footage, are they using the original pre graded scan of the SE that was done for the Blu-rays and then just scanning in the missing footage to make a “theatrical cut”?
EDIT: I’ve just found out the main why i can’t access anything :
Conversely I haven’t seen the EckhartsLadder video and can’t immediately find it among the dozens he’s posted in the last few months, so I can’t speak to whether his screenshots are the same as the reddit post.
