Well, that didn't take long.
In their wisdom, Disney and Marvel Studios decided against officially releasing the Avengers: Doomsday teaser trailer. Instead, the plan is to entice MCU fans into theaters, with four sneak peeks reportedly debuting over four weeks exclusively in front of Avatar: Fire and Ash.
While we could still get an HD version before the week is over, that's not looking overly likely. Now, a low-res "camrip" has found its way online, revealing the first of the teasers—revolving around Chris Evans' Steve Rogers—in its entirety.
Interestingly, it appears the countdown we've heard so much about ends in 100 days, on March 26, 2026. That's exactly a year to the day we got the four-hour cast reveal, suggesting we may get another with the rest of the ensemble's "surprise" characters.
The return of Evans as Captain America has been long suspected and is obviously huge. It's a shame that this is how we're learning about it, but this teaser is definitely unconventional and a cool way to confirm that the beloved MCU veteran is going to be forced to once again assemble alongside The Avengers, this time to battle Doctor Doom.
Steve got his happy ending in 2019's Avengers: Endgame when he travelled back in time to reunite with Peggy Carter. They've clearly since had a child, but if Cap's actions really did doom the Multiverse (that's the current rumour), his happiness is likely to be short-lived.
