Marvel’s New ‘Avengers: Doomsday’ Countdown Promo Reveals the MCU Homework Fans Can’t Skip

Marvel Studios is asking fans to do their homework before the next big team-up. ‘Avengers: Doomsday’ collates characters from Marvel’s Infinity and Multiverse Sagas for one big crossover event. With that much history packed into one film, the studio is giving audiences a map.

On August 16, Disney+ launched a 15-title ‘Countdown to Avengers: Doomsday‘ hub spanning 14 films and one series, with more than 42 hours of viewing. One outlet joked that it amounted to 15 films and shows in 15 weeks. The list got fans arguing over what was included and what was left out.

Now Marvel has distilled that homework into a new promo. Marvel Studios released a new ‘Countdown to Avengers: Doomsday’ trailer that compiles moments from essential MCU movies and TV series that will be important to the film. The spot also promotes the November 13 release of ‘Avengers Endgame: Encore’ on Disney+.

The 11 highlighted titles are ‘Avengers: Endgame Encore,’ ‘Black Panther: Wakanda Forever,’ ‘Captain America: Brave New World,’ ‘Avengers: Infinity War,’ ‘Thunderbolts*,’ ‘Shang-Chi and the Legend of the Ten Rings,’ ‘The Fantastic Four: First Steps,’ ‘Loki,’ ‘Captain America: The First Avenger,’ ‘Deadpool & Wolverine’ and ‘Doctor Strange in the Multiverse of Madness.’ ‘Loki’ is the only series featured in the trailer, despite the onslaught of new Marvel Disney+ shows in this latest saga. That is a pointed choice from a studio that has released a lot of television lately.

The promo uses Tom Holland’s Spider-Man from ‘Infinity War’ and Patrick Stewart’s Professor X from ‘Multiverse of Madness.’ Those clips signal that the film will pull in characters from well beyond the core Avengers lineup. Stewart, McKellen, Marsden, Cumming and other legacy X-Men stars are returning to the MCU.

The mix of old and new fits the film’s scale. ‘Captain America: The First Avenger’ and ‘The Avengers’ offer a refresher on the original versions of characters central to Marvel’s larger story, while ‘Infinity War’ and ‘Endgame’ revisit the previous Avengers event. With Chris Evans returning in ‘Doomsday,’ the ending of ‘Endgame’ could carry extra weight.

Some picks are about the multiverse. ‘Loki,’ ‘Spider-Man: No Way Home’ and ‘Multiverse of Madness’ all deal directly with alternate realities, while ‘Deadpool & Wolverine’ connects the MCU to characters from outside Marvel Studios’ original continuity. Of Marvel’s Disney+ series, ‘Loki’ engages most directly with the structural mechanics of the multiverse.

Others set up the modern roster. Anthony Mackie will return as Captain America in ‘Avengers: Doomsday,’ making ‘Brave New World’ required viewing. Shuri, M’Baku and Namor are all expected to be part of the film, which makes ‘Wakanda Forever’ one of the more straightforward recommendations.

The promo is not a complete catch-up course. The Countdown to Doomsday collection on Disney+ closely mirrors the longer watch list, but omits several films from it, including the Fox ‘X-Men’ movies and ‘Spider-Man: No Way Home,’ which may be due to licensing issues. IGN also noted that some films viewers would expect to see on the longer list, such as the ‘Guardians of the Galaxy’ films and ‘WandaVision,’ are absent.

Fans have noticed other gaps too. Fans have raised the absence of ‘The Marvels,’ among other titles, and the show’s role in the multiverse era keeps coming up in those debates. The trimmed list invites exactly that kind of argument.

‘Avengers: Doomsday’ arrives only in theaters everywhere on December 18. ‘Avengers: Secret Wars’ follows in 2027. That leaves roughly 5 weeks for anyone trying to work through the list.

For casual viewers, the promo makes the task feel manageable. For longtime fans, it is a signal about which stories Marvel thinks matter most as the Multiverse Saga heads toward its conclusion. Either way, the countdown is clearly on.
