Dune: Part Three IMAX with Laser superior in authorial intent to 70MM?
For The Odyssey: The cut 15/65mm original negative was the hero format, and the 5/70mm and 35mm exhibition formats were derived from it photochemically through contact and optical printing. The digital intermediate needed for digital cinema and home video was sourced from the 15/65mm timed contact interpositive.
For Dun3, I searched the lab workflow and found nothing published, no FotoKem credit, no statement on whether the 70mm prints come off a full DI film-out or a photochemical conform with the digital desert material filmed out and cut in. Villeneuve has talked about capture only.
The reasoning that makes a full DI likely is Villeneuve's VFX volume, which is nothing like Nolan's, plus native digital desert footage that has to reach celluloid somehow.
Thus I went with IMAX with Laser rather than the 70mm showing. I am obsessed with authorial intent, and thus would rather see it in the medium it was worked on by the most people, which in this case was probably the DI. Knowing Nolan's process, the inverse was true of The Odsys
