At the end of the Guardians Of The Galaxy Vol. 2 section of Marvel’s Comic-Con panel, Room‘s Brie Larson flew out from backstage like a sash-wearing, laser-blasting superhero and officially confirmed that she’s playing the Marvel Cinematic Universe’s incarnation of Carol Danvers, better known as Captain Marvel. Larson was first tied to the role in early June, when a rumor said that she was “in early talks” for the Captain Marvel movie. Now, those talks apparently went well, and Larson will be stepping into the bright red boots of one of Marvel’s most popular heroes when the movie comes out in 2018. (Or sooner, given the MCU’s love of post-credits stingers.)
