Latino-Review is now reporting that Ms. Marvel will in fact be in the sequel.
“Miss Marvel is the last piece of major casting left in the movie. Yeah, Miss Marvel. Now, I’m not going to spoil HOW she is in it, but she is in there kids.”
A few months ago Katee Sackhoff revealed that she had been talking to Marvel about a film project. A lot of people assumed that she could be up for the role of Ms. Marvel, which you’ve got to admit would be perfect casting. Still no official word on it but it can be a good choice.
