"We already have our hands full trying to tell the story we have without pre-existing characters," Anthony said.
"Anthony would probably die from exhaustion if we introduced another character," Joe said, while but his brother added: "That's not to say we're not going to introduce a new character."
When asked if the character in question could be Brie Larson as Captain Marvel, Anthony replied: "That's one we're going to have to plead the fifth on."

Joe said: "It would be perfect casting, and we're huge Anna Kendrick fans.
