Hollywood does not have many instances when rivalry is transformed into celebration. The majority of release-date battles are silent games of chicken in hopes that one of the studios will eventually blink and retreat. However, once in a while, a collision turns into a cultural phenomenon, something that fans can unite over.
‘Avengers: Doomsday’ and ‘Dune: Part Three’ are both currently scheduled to release on December 18, 2026, so that lightning can strike twice. And Simu Liu knows it.
Simu Liu Leans Into “Dunesday” As Marvel And Dune Prepare To Collide
The ‘Avengers: Doomsday’ star just contributed to the mounting hype by tweeting a bare but loaded message on X: “Prepare for DUNESDAY”. It was not a press release or a calculated quote; it was a well-timed joke. In just two words, Liu acknowledged that something bigger than a typical box office battle is brewing. It is not merely Marvel vs. Warner Bros. It is spectacle vs. spectacle, fandom vs. fandom, and, most crucially, cinema vs. cynicism.

December 18, 2026, is already one of the most discussed dates in the movie calendar, despite being a year away. On the one hand, there is ‘Avengers: Doomsday’, the next giant crossover of Marvel Studios and the foundation of the endgame of the Multiverse Saga. On the other hand is ‘Dune: Part Three’, the long-awaited follow-up to Denis Villeneuve’s adaptation of his own epic sci-fi, a franchise that has gradually increased in stature, size, and fan loyalty.
The internet, as it does best, immediately named the confrontation Dunesday. Now, Simu Liu’s tweet is one of the first instances when a key cast member of either movie has publicly accepted the moment. And that matters. When the actors recognize such fan-based movements rather than dismissing them, it justifies the excitement. It is an indication that competition does not always pose a threat to studios; in some cases, it is an opportunity.
It has already been speculated that one of the studios could relocate. Disney has started to release early trailers of ‘Avengers: Doomsday’, one of which caused a shockwave in the MCU community: Captain America is back. Warner Bros., in its turn, has redoubled its belief in ‘Dune: Part Three,’ standing its ground. And history indicates that both films may flourish. Theatrical success is not necessarily a zero-sum game, and mutual hype can transform a possible confrontation into a party. When viewers feel that they are a part of something, they turn up. And there are not many actors who know that better than Simu Liu.

Simu Liu’s passion has an added significance since he has already experienced a once-in-a-generation film experience. In 2023, he starred as one of the Kens in Greta Gerwig’s ‘Barbie’, released on the same day as Christopher Nolan’s ‘Oppenheimer’. What might have been a scheduling nightmare turned out to be a viral phenomenon, Barbenheimer, which made going to the movies a communal experience.

Audiences dressed up. They scheduled two-feature programs. The actors of both movies embraced the ridiculousness and the fun of it. What ensued was one of the largest theater victories in years. ‘Barbie’ has surpassed the billion-dollar mark, becoming a cultural juggernaut. Whereas ‘Oppenheimer’, a three-hour historical drama, shocked the world by making almost a billion dollars globally and proceeded to dominate awards season.
Liu himself saw the power of competition when it was welcomed instead of being feared to raise all boats. His Dunesday tweet seems less of a joke and more of a nod in that context. He realizes that fans do not simply desire content; they desire moments. They desire reasons to care, to be involved, to feel that going to the movies is important once again.
