Brie Larson: There are a ton of films with her. See Room, Free Fire, and Short Term 12.

Capitan Marvel: There haven't been any films that mention the character until the reveal at the end of Infinity War. If you want to read up on her, there's a long history of the character but I would start with her more recent series and Civil War 2 (which she's a big part of)

Other than that, I'm confused about your questions sir.
