I finally was able to watch this yesterday (wait for 70mm IMAX was insane) and it was incredible. How Nolan was able to keep me on the edge of my seat for what is essentially a biopic is a masterstroke. If they’re able to extend IMAX even further I definitely see 750m being a possibility.
Honestly surprised I still recommend people watch this in 70mm IMAX when it’s primarily just people talking yet Nolan pulled it off.
