Marvel’s New ‘Avengers: Doomsday’ Teaser Looks Back at the MCU as ‘Endgame Encore’ Heads to Disney+
Marvel is using its past to build excitement for ‘Avengers: Doomsday’. Robert Downey Jr. is back as Doctor Doom, and the directors who gave Tony Stark his goodbye are the ones bringing him back to Marvel in a different role. “Doomsday” takes over theaters on Dec. 18.
That nostalgia has already been a big part of the marketing. The Infinity Vision program began in September 2026 with Avengers: Endgame: Encore, a re-release of Avengers: Endgame (2019). When it was released in theaters, the slightly longer version of “Endgame” added four new scenes that tied into “Doomsday.”
Now Marvel has released a new teaser honoring the MCU ahead of the film. Marvel Studios has released a new “Countdown to ‘Doomsday'” TV spot and poster ahead of Avengers Endgame: Encore’s Disney+ debut on Friday, November 13. The clip, shared in the screenshot, opens on a moody blue-toned shot of a hand reaching toward a battered helmet, with Disney+ and ‘Avengers Endgame: Encore’ branding in the corner.
The extended cut is almost ready to stream. An updated cut of the 2019 movie, Avengers: Endgame: Encore, arrives on Disney+ November 13 with new scenes and color grading. That gives Marvel fans with a Disney+ subscription roughly one month to watch Avengers: Endgame: Encore before Avengers: Doomsday opens in theaters.

The changes are small but significant. While the bulk of the movie is the same, there are four new scenes that happen in the end credits. The film now has a runtime of 185 minutes, making it four minutes longer than the original theatrical cut. Marvel and Disney shot extra footage while making Doomsday, and they put the new scenes at the end of Encore to tease what’s to come.
The re-release did more than tease the next movie. It was also a hit at the box office, opening with $26 million domestically and $86 million globally when it returned to theaters. The re-release helped “Endgame” retake its spot at the top of the all-time box office charts, beating “Avatar” with $2.925 billion.

It also introduced Disney’s new premium format. Avengers: Endgame Encore introduced audiences to Infinity Vision, Marvel’s preferred premium format for watching Avengers: Doomsday, since Dune: Part Three is hogging all the IMAX screens. With no IMAX screens currently available, Disney and Marvel have turned to Infinity Vision to build hype for the “Avengers” sequel amid the “Dunesday” match-up coming on Dec. 18.

The teaser is part of a larger push on the streaming service. Disney+ has a collection for anyone planning a rewatch before December, along with a five-episode companion podcast hosted by Iman Vellani, who plays Ms. Marvel, and Frank Alvarez.

The podcast looks back at the Infinity Saga with Doomsday in mind. Each episode revisits an individual movie from the Infinity Saga and discusses what might still matter for the next Avengers movie. The last episode covers Endgame and dropped alongside the theatrical re-release.

The countdown is getting louder. Disney+ is positioning ‘Endgame Encore’ as a lead-in to the new film, saying it features new color grading and additional scenes linking to Marvel Studios’ Avengers: Doomsday, giving fans something extra to discover.

For many fans, rewatching the Avengers’ final fight against Thanos will be the perfect warm-up before Downey returns in a very different role. With the extended cut streaming on Friday, there’s plenty of time to catch up before Doom arrives.
Will you be rewatching ‘Avengers: Endgame Encore’ on Disney+ before ‘Avengers: Doomsday’ hits theaters?
