From the beginning, we wanted to shoot in film --- the traditional format for the Western. I grew up with my brother [director Christopher Nolan] shooting on film, and felt it remained the best image capture system available. But it's hard to reproduce the beauty of what we're getting in a broadcast environment. I'm very excited about the presentation we were able to do on HBO, but with UHD and HDR we were able to do something that's much more faithful to what we're shooting and get closer to the texture and density of colors of the film that we're making.
