Avengers: Doomsday directors Joe and Anthony Russo have confirmed that they are indeed the directors behind the extra long post-credits scene of Thunderbolts* with a message posted to their social media, urging fans to make sure to stick around for the end of the movie to get their first taste of Doomsday.
"If you haven’t seen Thunderbolts… Go now! @jakeschreier made a fantastic film!" reads the Russo brothers' post. "Congratulations to the entire cast and crew. And make sure to stay until the very end of the credits… we left you a little something."
Thunderbolts* director Jake Schreier previously disclosed that, though he was on set for it, the film's post-credits scene was actually directed by someone else, on the set of a different movie. It's now confirmed that, as Schreier hinted, that movie was Avengers: Doomsday and the directors were the Russos.
I'm about to get into some Thunderbolts* spoilers, so turn back now if you want to stay totally in the dark.
In the post-credits scene, set about a year after the events of the film, the Thunderbolts - now officially rechristened as the New Avengers - lament their rivalry with Sam Wilson/Captain America's own version of the Avengers, who are at odds with their own government sanctioned team.
However, their conversation is cut short by an alert which leads them to bring up a satellite view of the Fantastic Four's craft entering the atmosphere, presumably from their own alt-reality where The Fantastic Four: First Steps will take place.
This sets up Doomsday's massive cast, which, while not fully revealed, already includes the New Avengers, the Fantastic Four, and even many Fox X-Men.
