Disney+ Honors the MCU With a New ‘Doomsday’ Countdown Teaser

Marvel Studios is leaning on nostalgia as it heads toward ‘Avengers: Doomsday’. A new promotional teaser built around the Infinity Saga has landed just as the sequel’s theatrical release on Dec. 18 comes into view.

The spot is tied to ‘Avengers Endgame: Encore’, the updated version of the 2019 blockbuster that Disney+ is about to add to its library. Marvel is positioning it as the last stop before the next big team-up.

‘Encore’ first appeared in theaters in September as a re-release of ‘Avengers: Endgame’ with new color grading and extra scenes. Those scenes were reportedly shot during production on ‘Doomsday’ and attached to the older film, which is why they play more like a preview than a deleted scene.

The theatrical run lasted a little over 30 days. It even won its opening weekend at the box office, beating three brand new releases.

Joe Russo, who directed both films, has reportedly described the re-release as a bridge between the two movies and a critical companion story to ‘Doomsday’. Those remarks are known mainly through secondary outlets, so treat the exact wording with some caution.

Now Marvel has put out a fresh TV spot called ‘Countdown to Doomsday’, along with a new poster for the streaming release. The spot is available to watch ahead of ‘Encore’ arriving on Disney+ on Friday, Nov. 13. A 45-second cut of the promo has been circulating online, with ‘Universe’ on screen and the Nov. 13 date in the branding, though the full length of the official spot was not confirmed in the sources reviewed.

The campaign leans on how long the story has been building. Instead of showing new battle footage, it asks viewers to look back at where the saga started before the next chapter begins.

The updated cut runs 185 minutes, which is 4 minutes longer than the original. Marvel and Disney describe it as the film fans already know, with a few extra surprises.

Reports on the new material differ slightly. One account counts 4 new scenes that play in the end credits. Another review of the theatrical version describes roughly 5 minutes of new footage, including a new ending and 3 new post-credits scenes. The difference may come down to how the footage is counted, since the theatrical release reportedly varied the post-credits scenes depending on the screening.

That variation was a concern for fans who could not see every version in theaters. According to one report, the Disney+ release arrives with all of the extra scenes that were not viewable in every format. That would make the streaming version the most complete way to see the bridge material, though Disney has not detailed exactly how the scenes are arranged.

One reviewer of the theatrical cut was less impressed, saying there was not enough new footage to make the experience genuinely feel fresh. Whether the new teaser changes that view is a matter of taste.

The streaming date is part of a broader rollout. Disney+ has a ‘Countdown to Avengers: Doomsday’ collection for anyone planning a rewatch before December. It also hosts a 5-episode companion podcast with Iman Vellani, who plays Ms. Marvel, and Frank Alvarez. Each episode revisits one Infinity Saga movie and discusses what might still matter for the next film. The final episode covers ‘Endgame’.

Early on, the studio promoted ‘Encore’ as a theatrical event, and the Disney+ landing page initially featured only the trailer. Some outlets warned the extras might stay exclusive to cinemas. Others guessed the streaming debut would land around Thanksgiving.

Disney chose the earlier date instead. That leaves about 5 weeks between the ‘Encore’ streaming debut and the opening of ‘Doomsday’.

For Marvel, the schedule does two jobs. It gives viewers who skipped the theatrical run time to catch up on the bridge scenes. It also keeps the Infinity Saga in front of audiences just as the next Avengers story prepares to open.

The strategy has already been tested at the box office. The theatrical ‘Encore’ run helped push ‘Endgame’ to a new international milestone, according to coverage of the re-release.

What the new teaser does not reveal is any fresh look at ‘Doomsday’ itself. For now, the pitch is simple: rewatch the old story, spot the new connections and arrive in December ready.
