Everyday Basis

Fewer than 50 theaters worldwide can show IMAX 70mm film, and dune 3 imax 70mm tickets for 19 locations went on sale on April 6, 2026 and sold out within minutes. If you want to know whether a listing is the rare film format or a standard IMAX screening, and what that difference means before the December 18, 2026 US release, the key is understanding how the format works and what details to check.

Why IMAX 70mm stands out

IMAX 70mm uses 70mm film with 15 perforations per frame running horizontally. That layout is why the format is also called IMAX 15/70. A larger film frame carries more image information because each frame takes up more physical area on the film strip.

The IMAX 70mm frame measures about 70mm by 48.5mm and has a native aspect ratio of 1.43:1. That taller shape changes what you see on screen because it fills more vertical space than digital IMAX, which typically uses a 1.90:1 aspect ratio.

Resolution is part of the draw. IMAX 70mm film has a native resolution of up to 16K, while digital IMAX theaters max out at 4K. The format can also play on screens up to 59 by 79 feet, so the image difference is not only about sharpness but also about how much of your field of view the screen can occupy.

Running that much image through a projector takes more material. IMAX 70mm requires three times the length of film stock as standard 65mm film for the same duration, and IMAX 70mm projectors use a horizontal rolling loop movement to move the film through the machine.

How the movie connects to the format

Dune: Part Three is directed by Denis Villeneuve and is based on Dune Messiah by Frank Herbert. The production used a combination of 65mm film and IMAX 15/70mm film cameras, with some desert scenes shot digitally.

That mixed capture matters because an IMAX 70mm release is tied to material created for large-format presentation. The movie also received a three-week IMAX theater exclusivity period over Avengers: Doomsday due to being filmed in IMAX 70mm format, which shows how strongly the release is linked to that presentation.

Format names can cause confusion

The easiest mistake is assuming every IMAX showtime is the same. Dune: Part Three will be released in IMAX 70mm in select theaters, not in every IMAX auditorium. A listing that only says IMAX does not establish that it is the 70mm film version.

The reason is simple: IMAX is a theater brand and presentation system, while IMAX 70mm is a specific film format. Because digital IMAX usually uses a 1.90:1 aspect ratio and maxes out at 4K, the label alone does not tell you whether you are getting the taller 1.43:1 film presentation or a digital one.

Availability is the second complication. There are fewer than 50 IMAX 70mm-capable theaters worldwide as of 2026, so even major US markets may have limited or no access to the format. That scarcity helps explain why tickets for 19 locations sold out within minutes when sales opened.

Timing is the third complication. Dune: Part Three is scheduled for theatrical release in the United States on December 18, 2026, but the pace of early ticket sales means waiting to compare options may leave only non-70mm showtimes. If IMAX 70mm is your priority, the release date and the ticket-on-sale date are two separate checkpoints.

What to check before you buy

Start with the showtime label. You want a listing that specifically identifies IMAX 70mm, also called IMAX 15/70, rather than a listing that only says IMAX.

Next, check whether your theater is one of the select locations offering the film format. Because fewer than 50 theaters worldwide are IMAX 70mm-capable, the default assumption should be that a nearby IMAX screen is digital unless the listing confirms otherwise.

Then check timing. Tickets for 19 IMAX 70mm locations already went on sale on April 6, 2026 and sold out within minutes, so a buyer choosing between formats needs to decide early whether the rare format is worth planning around.

Release timeline to watch

If your goal is the rarest presentation, verify the words IMAX 70mm or IMAX 15/70 on the ticket page first, then act on sale timing rather than waiting for the general release window.
