Brie Larson just wrapped her run in the UK stage play Elektra and is already sparking speculation about her return as Captain Marvel in Avengers: Doomsday.
That’s not all, as it’s also been learned that Larson will be appearing at Comic Con Liverpool this November—possibly suggesting she’s sticking around the UK, where Avengers: Doomsday is filming or expected to be filming later this year.
Adding fuel to the fire, Larson is listed as part of the recently rumored 60-member cast of Avengers: Doomsday.

Brie Larson finished Elektra
Tuesday on Instagram, Larson, who shaved her head for the role, shared images and a message about her time performing Elektra at the Duke of York’s Theatre, marking its conclusion. The timing lines up perfectly with the start of filming on Avengers: Doomsday in the UK:
It’s taken me a minute to even remotely have the words to express what Elektra has meant to me. We shared something special during our time at the Duke of Yorks. As a company we laughed, sang, screamed, cried, learned how to sing “no” 100 different ways, got stronger physically and mentally, stayed connected as a unit, enjoyed cocktails hours, risked it all every show, danced at gay clubs, played games, and spoke with thousands and thousands of you at stage door. We were lead by an incredible team of creatives. And we loved every second of it. I didn’t realize how much I needed community and human interaction until this experience. It’s an honor of a lifetime to share these moments together. Thank you from the bottom of my heart. It’s not lost on me that many had to travel far distances, and spend hard earned money to see us. You made it what it was, and we couldn’t have done it without you. It’s going to take a long time to unravel the riches I acquired. But know I have never been happier than giving you everything I had, every night, and I can’t wait to keep doing that in new ways. Here are some of the bittersweet fragments of that glorious last time. I’m raising a glass to what it was.

Will Captain Marvel make it out of Avengers: Doomsday alive?
The last we saw of Brie Larson as Captain Marvel was in The Marvels, where she teamed up with Monica Rambeau and Kamala Khan to stop a multiversal threat—and helped set up the formation of what appears to be the Young Avengers team in the post-credits scene.
The Marvels mega-bombed at the box office with only $206M worldwide which followed the $1.13 billion dollar Captain Marvel movie, so similar to Avengers: Endgame, just how much Brie Larson appears in Avengers: Doomsday is anyone’s guess.
The Russos return to direct, where it was actually said they wrote Brie Larson out of Endgame and only featured her in the beginning and at the end, so it might be safe to say not to expect a lot of Captain Marvel in Doomsday, assuming she even appears and isn’t “busy” out in space doing something else.
It will also be interesting to see how many of these characters make it out of Doomsday alive. It’s already been said Avengers: Doomsday and Secret Wars will be something of an MCU soft reboot, so what could be happening is that Marvel is using the movies to get rid of characters that haven’t been successful with the MCU audience, such as Brie Larson’s Captain Marvel and Iman Vellani’s Ms. Marvel. Something similar just went down in Thunderbolts.
