You’ve no doubt heard some version of the Robert Burns adage about the best-laid plans. Marvel Studios had an elaborate marketing plan in place to introduce four teaser trailers for Avengers: Doomsday as previews prior to screenings of Avatar: Fire and Ash, with one teaser rolling out each successive week. But the first one leaked online a few days early, revealing that (as rumored) Steve Rogers/Captain America (Chris Evans) will appear and will have a newborn baby, presumably with Hayley Atwell’s Peggy Carter.

 

So maybe you’ve seen a bootleg version floating around the Internet, but Marvel has now released the HD version to the public. Merry Christmas! And we can look forward to three more: one focused on Thor, one on Doctor Doom, and the final one is purportedly a more traditional teaser trailer.

 

As previously reported, Marvel Studios originally planned to build its Phase Six Avengers arc (The Kang Dynasty) around Jonathan Majors’ Kang the Conqueror (and associated variants), introduced in Loki and Ant-Man and the Wasp: Quantumania. But then Majors was convicted of domestic violence, and Marvel fired the actor soon after. That meant the studio needed to retool its Phase Six plans, culminating in the announced return of the Russo brothers, who directed four of the Marvel Cinematic Universe’s most successful films, which brought in more than $6 billion at the global box office.

 

Rather than keeping Kang as the villain and recasting the character, the Russo brothers decided to take a new direction: bringing the Secret Wars storyline to the big screen. It’s one of their favorites but before they could take on Avengers: Secret Wars (slated for May 2027), the duo knew they first had to make Avengers: Doomsday, featuring the wildly popular comics villain Doctor Doom, featuring the return of Robert Downey Jr. to the MCU in that role.

 

Downey Jr. might be playing a new role, but Marvel is really getting the band(s) back together on this one. The film takes place 14 months after the events of this year’s Thunderbolts*.  So we’ve got Avengers favorites Thor (Chris Hemsworth), the new Captain America (Anthony Mackie), Bucky Barnes (Sebastian Stan), Ant-Man (Paul Rudd), Falcon (Danny Ramirez), and Loki (Tom Hiddleston). Then there’s the Wakandan contingent: Shuri as the new Black Panther (Letitia Wright), M’Baku (Winston Duke), and Namor (Tenoch Huerta Mejia).

 

Naturally, the Thunderbolts* (aka New Avengers) will appear: John Walker/US Agent (Wyatt Russell), Yelena Belova (Florence Pugh), Bob/Sentry (Lewis Pullman), Red Guardian (David Harbour), and Ghost (Hannah John-Kamen). So will the Fantastic Four: Reed Richards (Pedro Pascal), Sue Storm (Vanessa Kirby), Ben Grimm (Ebon Moss-Bachrach), and Johnny Storm (Joseph Quinn). But we also have the original X-Men: Charles Xavier (Patrick Stewart), Beast (Kelsey Grammer), Magneto (Ian McKellen), Mystique (Rebecca Romijn), Nightcrawler (Alan Cumming), and Cyclops (James Marsden).

 

For good measure, Marvel threw in Gambit (Channing Tatum) and Xu Shang-Chi (Simu Liu). There will also be plenty of cameos, like the Steve Rogers appearance that was recently revealed. We can expect to see  (at least briefly) Peggy Carter, Spider-Man (Tom Holland), Hawkeye (Jeremy Renner), and Doctor Strange (Benedict Cumberbatch), among others.

 

Avengers: Doomsday hits theaters on December 18, 2026. Avengers: Secret Wars is currently slated for release on December 17, 2027, and will mark the conclusion of the MCU’s Phase Six.
