Disney’s next major Marvel Studios release, Avengers: Doomsday, is building major momentum as insiders report studio executives are thrilled with early footage. The film is expected to dominate the holiday box office in December, yet it may face tougher competition than expected. Warner Bros. has confirmed that Denis Villeneuve’s Dune: Part Three will open on the very same weekend, setting up one of the biggest theatrical showdowns in years.
The two blockbusters are scheduled to release on December 18, 2026, a date fans have already dubbed “Dunesday.” Historically, few studios have dared to release a major film against a Marvel title. This time, Warner Bros. seems ready to challenge Disney’s long-running box office supremacy. The studio just landed an edge that could matter. According to Discussing Film, Dune: Part Three will be the only movie opening that weekend to screen in IMAX theaters across the U.S. Avengers: Doomsday will only receive IMAX placement overseas.
That exclusive access means Dune: Part Three will be the sole option for American audiences seeking the most immersive theater experience. IMAX screenings regularly count for a growing slice of box office revenue. For example, Oppenheimer earned about $190 million from IMAX screens in 2023, while Avatar: Fire and Ash saw $185 million in the format during its $1.47 billion global run. Premium screens are now a decisive factor for blockbusters chasing billion-dollar totals.
By locking down IMAX in the U.S., Warner Bros. is attempting to blunt Disney’s usual market advantage. The move shuts Avengers: Doomsday out of a premium pricing tier that could have increased early ticket sales. Still, Disney’s confidence seems high. Sources close to production say the film will be ready well ahead of its December debut. If the studio views the release date as a real threat, they could always shift it slightly earlier. So far, there’s no sign they will.
Avengers: Doomsday is already being projected as a multi-billion-dollar global event. Discussion among analysts suggests that even without IMAX showings in America, the Marvel juggernaut could easily surpass Avatar: Fire and Ash and move beyond the $2 billion mark. Meanwhile, Villeneuve’s first two Dune entries have earned a combined $1.1 billion, including $715 million from Dune: Part Two in 2024. The numbers set up a compelling fight for audience dollars during the holiday season, and both studios appear unwilling to blink.
With production on Avengers: Doomsday nearing completion and Dune: Part Three entering its final post-production phase, the clash between Disney and Warner Bros. will test more than just fan loyalty. It will also show how much premium-format screens matter in a theatrical market still finding its footing. Either way, this December’s box office battle is shaping up as the movie industry’s biggest duel in years.
