As the hype train for Avengers: Doomsday picks up steam, the realization that Dune: Part 3 shares the same release date as Marvel’s behemoth is spreading across social media — and Shang Chi star Simu Liu has come up for the perfect name for this double bill: DUNESDAY.
At the time of this article’s publication, Denis Villeneuve’s Dune: Part 3 is still on track for release on December 18, 2026 — the same day as Avengers: Doomsday. This heavyweight science fiction blockbuster clash will be a bonanza for theaters and cinemagoers, you’d imagine. But can it prove to be 2026’s version of the ‘Barbenheimer’ phenomenon of the summer of 2023?
For now, it’s all hype. Simu Liu, who is set to reprise his role as Shang-Chi in Avengers: Doomsday, took to Twitter / X to declare: “Prepare for DUNESDAY.”
