Marvel Studios made a long-rumored casting official today, and the Marvel Cinematic Universe has its Carol Danvers. During a lively Hall H panel at Comic-Con International, the studio confirmed "Room" star and Academy Award-winning actor Brie Larson in the role. She'll make her first appearance in the upcoming "Avengers: Infinity War" and headline a "Captain Marvel" solo movie currently scheduled for release March 8, 2019.

Larson was reportedly in negotiations for the role in early June. After the panel, she posted a photo of herself wearing a Marvel Studios hat with the caption, "Call me Captain Marvel."

Written by Nicole Perlman ("Guardians of the Galaxy") and Meg LeFauve ("Inside Out"), "Captain Marvel" is scheduled for release on March 8, 2019. No director has yet been announced.
