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.)

With Captain Marvel officially locked down, the last big hole from the five-year plan Marvel laid out in 2014—other than Inhumans, which might not be coming at all—has finally been filled in. That means, after the second part of Avengers: Infinity War, the entire future of the Marvel Cinematic Universe is a great big mystery. Isn’t that exciting?
