Brie Larson is absolutely the right choice for the upcoming Marvel movie, Captain Marvel. Some fans are concerned that she has never done an action film before but most people agree that she is a great choice for the character. She is an Oscar winning actress and starred in one of the arguably best movies of 2018 called Room.
I think Brie Larson will be exceptional playing the role, especially if the film provides some backstory from the comic books like her alcoholism. She also fits the role in terms of her appearance. Marvel films always have an amazing cast, even if they aren't very well known so I am sure they made the right decision in casting Brie Larson.
