Why is Avengers: Doomsday not playing in IMAX?

Because Dune: Part Three has them, and both films open on the same day. Avengers: Doomsday and Dune: Part Three both open Friday, December 18, 2026. IMAX confirmed in an investor presentation, reported in February 2026, that Dune takes precedence on US IMAX screens for that opening. IMAX is a single chain of screens that can run one film at a time, so the second title does not get them. Disney’s answer was not to wait: it launched its own premium-format certification program.

The evidence

The confirmation came from IMAX, not from either studio.

The claim traces to IMAX’s own investor presentation, slide 13, reported by two outlets on February 26, 2026. Neither Disney nor Warner Bros. announced it, and neither confirmed anything for this page.

How long it lasts is genuinely disputed, and the sources differ in quality.

The version that traces to the IMAX investor presentation describes the opening weekend. A widely repeated three-week version traces to a post on the account Empire City Box Office on X, reported by a film blog that hedged it with “apparently”. Both AI answer engines we measured gave the three-week figure.

Disney launched a competing format seven weeks later.

Disney announced Infinity Vision, its own premium large-format certification program, at CinemaCon on April 16, 2026, and reported more than 7,500 screen certification applications by late June. IMAX’s own chief financial officer called it a marketing play. That response is a revealed price for premium-format access, and it is larger than one weekend of forgone premium tickets.

Doomsday still leads every demand measure we took.

On October 24, 2026 the head search term ran 1,220,000 against 60,500, a 95.3% share. Trailer searches 96.8%, official-trailer comments 86.1%, trailer views 64.9%. Ticket searches, the measure closest to buying, is the narrowest at 73.2%.

What would have to be true for this to be wrong

If IMAX and premium large format are a small enough share of opening gross, the allocation is a story rather than a constraint — Disney insiders have pointed to titles that cleared a billion dollars without IMAX. The counter-evidence is Disney’s own behavior: a company that thought the screens did not matter would not have built a certification program for them.
