Marvel’s New ‘Avengers: Doomsday’ Countdown Promo Highlights the MCU’s Must-Watch Titles

‘Avengers: Doomsday’ is one of the biggest crossovers Marvel has attempted. The film will feature different groups of heroes from different universes, including the Avengers, the Wakandans from Black Panther, the Thunderbolts (known as the New Avengers) from Earth-616, the Fantastic Four from Earth-828, and the original X-Men. With so many storylines coming together, Marvel has been helping fans catch up.

The studio first did that through Disney+. Disney Plus officially unveiled its “Countdown to Avengers: Doomsday” section on the platform, showcasing the library of Marvel movies and TV shows that Marvel Studios itself has hand-selected as the must-see projects ahead of the big Avengers: Doomsday release in December.

The collection includes the Countdown to Avengers: Doomsday Official Podcast, hosted by Iman Vellani (Ms. Marvel) and Frank Alvarez, which revisits key films from the Infinity Saga with commentary and speculation.

Now Marvel has distilled that list into a new promo. Marvel Studios has released a new Countdown to Avengers: Doomsday teaser that draws on several essential MCU films, and according to The Direct, the spot highlights 11 projects.

They 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 and Wolverine’ and ‘Doctor Strange in the Multiverse of Madness’.

Some picks speak directly to returning characters. The origins of Steve and Peggy’s romance, plus Steve’s sacrifice, are all featured in Captain America: The First Avenger, which makes it a must-see before Avengers: Doomsday. Mackie will return as Captain America in Avengers: Doomsday, making his solo movie required viewing.

Others set up the multiverse rules. ‘Doctor Strange in the Multiverse of Madness’ formally introduces the concept of Incursions—the apocalyptic phenomenon where two universes collide, destroying one or both. The promo also includes a clip of Patrick Stewart’s Professor X from that film.

Only one Disney+ series made the cut. Despite an onslaught of new Marvel Disney+ shows in this latest MCU Saga, Loki is the only series featured in the Countdown to Avengers: Doomsday trailer. That makes sense given how central the show has become to the franchise’s multiverse storytelling.

Loki’s two seasons have been described as essential for understanding how the multiverse functions. The trailer also uses a clip of Tom Holland’s Spider-Man from ‘Avengers: Infinity War’.

The promo is a trimmed-down version of Marvel’s longer watch guide. The full Disney+ collection also includes X-Men, X2, The Avengers, Avengers: Endgame, and Spider-Man: No Way Home, alongside the titles in the trailer.

The inclusion of the Fox ‘X-Men’ films reflects the movie’s ambitions. With the “original” Fox X-Men confirmed to represent one of the three converging universes in Doomsday, those films allow fans to revisit where their cinematic journey began.

The new spot arrives alongside a major streaming release. Disney+ has set the release date for ‘Avengers: Endgame: Encore’ for Friday, November 13. The epic conclusion to the Infinity Saga, which has grossed more than $2.9 billion at the worldwide box office, includes a first look at Avengers: Doomsday ahead of its December 18 theatrical release.
