A new Avengers: Doomsday graphic appeared on the Fandango app overnight, showing the film’s December 18, 2026 release date next to a “Watch Trailer” button. The screenshot started circulating this morning, right as premium Infinity Vision tickets for Doomsday go on sale, along with tickets for the Avengers: Endgame theatrical encore.
We will update this article the moment we know whether the trailer drops, or doesn’t, at 9 am. It has officially been released. See the trailer below.
As we covered earlier this week, Disney opened this early ticket window specifically for Infinity Vision, the new premium large format Disney created after Warner Bros. locked down IMAX access for Dune: Part Three around the shared December 18 release. The Endgame Encore returns to theaters September 25 with new footage and a post-credits scene that connects directly into Doomsday. Disney has also listed a preliminary Doomsday runtime of 165 minutes, longer than Infinity War and shorter than the original Endgame.
For those looking for Avengers: Endgame and Avengers: Doomsday popcorn bucket release info, while we cannot confirm anything, and things change all the time, we are hearing that for Endgame, two major buckets are coming along with the regular tins and tumblers. An Iron Man (Endgame) Premium Head Helmet popcorn bucket, and a Gauntlet (we just don’t know if it is the Thanos or Iron Man version). Avengers: Doomsday is harder to pin down, but we do know of a Doomsday Head Bucket that resembles the Skeletor Bucket that was recently released for He-Man. Keep up to date with all the latest Movie Theater Popcorn Buckets!
Marvel has already released four teaser trailers for Doomsday, each built around a different corner of the cast. The first confirmed Chris Evans is back as Steve Rogers. The second turned the spotlight on Chris Hemsworth’s Thor. The third brought in the X-Men, with Patrick Stewart’s Professor X, Ian McKellen’s Magneto, and James Marsden’s Cyclops sharing the screen. The fourth closed things out with Letitia Wright’s Shuri, Ebon Moss-Bachrach’s The Thing, Winston Duke’s M’Baku, and Tenoch Huerta Mejía’s Namor.
A full trailer already screened for attendees at CinemaCon months ago, and today’s tease could be that same footage finally going public rather than brand new material. That would also explain the timing. Marvel is set to return to Hall H at San Diego Comic-Con this Saturday, July 25, for its first MCU panel there in years, and releasing the CinemaCon footage today would build momentum heading into that panel instead of competing with it.
Nothing is confirmed yet on Marvel’s end, and the Fandango graphic could simply be a placeholder ahead of a slightly later reveal. But between the ticket sales going live today and the SDCC panel just days away, this is about as loud a signal as fans have gotten that the CinemaCon trailer is finally coming home.
Avengers: Doomsday hits theaters December 18, 2026.
