VIDEO Here's why The Hateful Eight shot on 65mm film
That's because the filmmaker managed to convince the studio to let him shoot on 65mm film and with expensive lenses which haven't been used in years, all with the intention of releasing the film in an exclusive early 'Roadshow' version just for outlets capable of projecting film at 70mm.
Now this video explains why 65mm and Ultra Panavision are important, and shows just how enthusiastic everyone was about the process. It's also narrated by Samuel L Jackson, which is always fun.
