A three-minute informercial about Chris Nolan‘s Oppenheimer (Universal, 7.21) and especially about the technical grandeur of 70mm IMAX, addressing the technical immersives and whatnot, and they can’t specifically state which aspect ratio Oppenheimer will be shown in — the preferred 1.43:1 or the less preferred 1.78:1 or 1.90:1?

Hardcore 70mm IMAX has to be projected at 1.43:1…period. 1.43 is taller than fuck, and not that far away from classic “HE boxy” (i.e., 1.37 or 1.33). Trust me — it’s the only way to go.

1.78:1 or 1.90:1, which is how a significant portion of Nolan’s Dunkirk was presented, doesn’t get it.

How much of Dunkirk was presented within 1.43? Wikipage: “The film [used] both IMAX 65 mm and 65 mm large format film stock in Panavision System 65, with more IMAX footage than in any of Nolan’s previous films — an estimated 75%. The sparsity of dialogue made it possible for IMAX cameras, which are notoriously noisy, to be used as the primary format.”

I know that Dunkirk switches back and forth a lot between 1.90 and 1.43, and that my basic reaction was “why wasn’t it an all-IMAX thing?” I don’t want any of that shit when I see Oppenheimer — I want a pure 1.43 experience, start to finish.

The 1.90:1 aspect ratio, of course, is right next to 2:1, which Vittorio Storaro was a big supporter of (he called it Univisium). Fine, but 1.90 is not IMAX — not really.
