Marvel’s forthcoming Captain Marvel is kind of a big deal: it will be the studio’s first official super-heroine film. Captain Marvel is on her way to leading one side of Marvel’s latest event, Civil War II, and has a dedicated fan following which has kept her standalone title alive for years.

Now, sources close to Variety are reporting that Marvel is in the process of casting the role, and Brie Larson (Room) is in early talks for the role. Sources say that she’s the studio’s top pick.

While no director has been tapped for Captain Marvel just yet, writers Meg LeFauve (Inside Out) and Nicole Perlman (Guardians of the Galaxy) are already on board. Marvel’s Kevin Feige will produce the film.

Captain Marvel’s casting has been hotly debated for some time; fans have argued for the viability of actresses like Natalie Dormer, Charlize Theron, and Katee Sackhoff. Details on other elements of the movie are under wraps for now, but if the story sticks with Carol Danvers’s origins, the character will be a U.S. Air Force officer who gains superpowers after her DNA fuses with an alien’s after a freak accident. So far, Marvel has released no other details on the film, which is scheduled to release on July 6th, 2018.
