That possibility is now hanging over Avengers: Doomsday. According to recent industry chatter, Marvel’s next major event film may not receive an IMAX debut, as Dune: Part Three is reportedly set to claim exclusive access to IMAX screens for its first three weeks in December 2026. If accurate, this would mark a notable shift for Marvel, a studio that has increasingly relied on premium formats to supercharge opening weekends and maximize box office returns.

With a limited number of IMAX screens available — particularly during the packed holiday release period — being excluded from the format could have a tangible impact on Avengers: Doomsday’s financial performance. Premium-format tickets often generate a significant portion of a blockbuster’s revenue, and audiences have come to expect Avengers films to be experienced on the biggest screens possible. Launching without IMAX could soften the film’s event status, forcing it to depend on standard and alternative premium formats instead.

At the same time, Warner Bros.’ strong commitment to Dune: Part Three highlights just how competitive the landscape has become. As two blockbuster franchises vie for attention — and premium screen space — December 2026 is shaping up to be a high-stakes showdown where release strategy may prove just as critical as audience enthusiasm.
