IMAX battle heats up 'Dunesday' box office war
19 Oct
Summary
- Two major blockbusters are set to release on December 18, 2026.
- IMAX screens are secured exclusively by Dune for its opening three weekends.
- Avengers: Doomsday introduces Infinity Vision as a premium screen alternative.

The holiday season of 2026 is poised for a monumental box office showdown as Denis Villeneuve's 'Dune: Part Three' and the Russo brothers' 'Avengers: Doomsday' are scheduled for a direct collision on December 18, 2026. This highly anticipated clash, already dubbed 'Dunesday', marks a significant event in the cinematic calendar, with both studios vying for supremacy.
Warner Bros. has secured the premiere 70mm IMAX screenings for 'Dune: Part Three' for its initial three weekends, presenting a significant challenge for 'Avengers: Doomsday'. In response, Disney has launched 'Infinity Vision', a new certification for premium large-format screens, to offer audiences a comparable high-quality viewing experience for the superhero epic.
While both films share a US release date of December 18, 2026, 'Avengers: Doomsday' is slated for an earlier rollout in select international markets, with December 16 releases planned for the UK, China, France, Malaysia, and Singapore. Other territories, including India, Australia, and Mexico, are scheduled for December 17 releases.
