We went to watch the Oppenheimer in IMAX 70mm, and it was a heartwarming experience. We were blessed with two cinemas in the SF Bay area, but still need an hour drive and early booking many weeks prior. Like
@Kilgallb said, once you immerse in the story you kinda forget about the format. But to watch Oppenheimer on IMAX 70mm is definitely an experience I would treasure for years to come. I heard they might re-screen some older 70mm titles such as Interstellar.
And a happy surprise upon exit, we were gifted with a 70mm film strip for each ticket holder. I have to applaud Christopher Nolan for educating moviegoers to appreciate the analog 70mm format.
Attached below the gift film strip: the image is actually a bit narrower in the middle, probably due to multi-channel audio tracks on the edge. I have shot 35mm to 70mm color slides, and hope Nolan and his friends in the movie industry can keep this format alive and thrive. So we still film shooters can pick up some crumbs (like the Ektachrome 100D re-spooled in 35mm)
