Joe and Anthony Russo hit the Deadline Studios at SXSW London on Tuesday in the company of Avengers: Doomsday and Avengers: Secret Wars collaborator Donald Mustard.

The trio confirmed they are currently in the throes of post-production on Avengers: Doomsday and pre-production on Avengers: Secret Wars ahead of respective planned releases in December 2026 and December 2027 releases.

Quizzed on whether they planned to work on future Avenger films, Anthony Russo suggested that they were done with the franchise for now but did not rule out future Marvel collaborations.

“When we did Endgame we were like, we’ve completed it. It was our fourth Marvel film though. We had completed a story arc that we began in the Winter Soldier and for us it was very much intended to be an ending,” said Anthony Russo

“So, I will say this. The stories that we’re focused on now are complete. Doomsday and Secret Wars speak with one another as two films and they form a complete expression. Whether or not we all collaborate with Marvel beyond that is certainly a possibility, but right now, the vision, the narrative vision is just for Secret Wars.”

“We’re going to see what we look like in photos in 2028 and then we’ll let you know,” joked Joe Russo, who also gave a small update on where they are at with both films.

“We are doing some work still on Doomsday and will be until probably they rip it out of our hands in November and that just means they have to give it to other people, to finish it for a few weeks, and then we’re in the middle of what we would call pre-production… we like doing many things at the same time,” said Joe Russo.

The Avenger movies see the Russo Brothers’ AGBO company collaborate once again with Marvel Studios parent company the Walt Disney Studios.

“Our relationship with Marvel has built over many years now and there’s been a very fruitful relationship. We’ve done some of our best work with Marvel. We really value the relationship and I think they really value what we have brought to the MCU,” said Anthony Russo.

Former Fortnite creator and Epic Games Chief Creative Officer Mustard, who joined AGBO in 2023 to help oversee the company’s push into interactive and immersive experiences, hinted interactive elements are in the works for Avengers: Doomsday.

“We were all there together kind of figuring out what that movie is and what is going to be seen this Christmas. It’s just an amazing partnership and we’re building all sorts of things together that kind of fuse our approach to telling stories,” he said.
