While promoting his new movie Dunkirk, which hits theaters on July 21, Christopher Nolan confirmed that hes remastering his previous movies (such as the Dark Knight Trilogy) in 4K.
Nolan told BadTaste.it that he is personally involved in the 4K remastering process, and he seemed pretty excited about it. He explained that 4K with HDR technology gets the home video audience closer to the 6K resolution his movies were shot on, though the IMAX scenes are at a massive 18K. Check out his comments in the video below.
