Ironic that the backwater English city I’m from had one, but then Melbourne Museum is the only one for the entire Southern Hemisphere.
In Nolan’s defence I don’t think seeing it in IMAX is that big a deal. I’ve seen at least Dark Knight Rises, Interstellar and Furiosa in IMAX, movie-wise, and don’t feel like it adds that much. The point of IMAX is that you feel like you’re on a space walk from the shuttle, flying down a canyon or whatever, and you can look around and see more stuff. In a movie the action is by both necessity and convention restricted to a point-of-attention within the frame, often drawing your eye with tricks like focus pulls to show what it wants you to see. Transpose that to the IMAX format and you just end up with a lot of peripheral backdrop, none of which you want to be paying attention to when there’s stuff going on.
I didn’t see Oppenheimer in IMAX, and that was mostly close-ups of men looking constipated in rooms. It made more sense when Nolan did the gliding bit in Hong Kong in IMAX, and Interstellar had shots portraying the emptiness of space really well, both of which are like call-backs to classic IMAX reels.
