Sometimes the fan campaigning really works, though in this case, the fan is actor Giancarlo Esposito, known for his roles in “Breaking Bad,” and “The Mandalorian.” In the last year or more, Esposito has made it no secret that he’s been eager to join the Marvel Cinematic Universe, seemingly talking it up every chance he gets and telling audiences. Previously, the actor revealed he had met with Marvel Studios and said he was keen to play a new version of Professor X in the “X-Men” movies.
