10 Things You Need To Know About Avengers: Infinity War
3. Captain Marvel Is Definitely In It
Brie Larson was cast as Captain Marvel a while back, though there never seemed to be a consistent word on whether or not she would be appearing in Infinity War...until a casting sheet for the movie leaked last December.
The casting call mentioned Larson and Captain Marvel by name as appearing in the film, which makes it clear that she'll have some sort of involvement ahead of her own solo movie releasing just two months before The Avengers 4.
Whether she'll simply appear in Infinity War's post-credits scene to set up her own solo movie or will have a more substantial part remains to be seen, but she'll be in there somewhere.
