Fans have been wondering if Marvel Studios would flinch now that Dune: Part Three and Avengers: Doomsday are both set to hit theaters on December 18, 2026. During a recent appearance on Josh Horowitz's Happy Sad Confused podcast, the Marvel Studios president was asked directly, "Doomsday sticking to its release date?" The timing makes this one of the most fascinating release date battles Hollywood has seen in years. Denis Villeneuve's Dune: Part Three recently unveiled a new poster while confirming it will keep its December 18, 2026 release date. With Feige confirming Marvel isn't changing course, the stage is officially set.
