Watch one projectionist’s timelapse view of “The Hateful Eight” roadshow from the booth. Andrew Walker notes, “I was lucky enough to be one of the projectionists to work on the 70mm roadshow for The Hateful Eight and this is what I captured during the 59 showings the film over the course of 15 days. The whole thing was quite an experience and it made me appreciate film all over again. Shot with a Nikon D810 using the Kessler TLS system and a Second Shooter.”
