We'd imagine you'd learn all sorts of things if you were cast as a Marvel superhero.
But what you didn't think of is how to look cool, as Brie Larson found out when she was training for the role of Captain Marvel.

And yes, there is someone who teaches how to do just that. There's a mix of bending your knees, clenching your fists, and turning your head first. No smiling, of course.
Speaking of being cool, Larson also wants to get on those trips to Italy that Magic Johnson and Samuel L. Jackson have a good time on.
"I've never been invited!" she said. "What do I gotta do?"
