Remember when Kevin Feige said that Marvel was about to enter its mutant era? Well, it's here. Avengers: Doomsday is exciting and all, but there's one superhero team that has yet to be introduced in the Marvel Cinematic Universe... and that's the X-Men, baby.
Not only is a new X-Men movie in the works, but we have a cast, a director, and a release date. Spider-Man: Brand New Day officially introduced us to Sadie Sink's Jean Grey, and the cast announcements haven't stopped coming since.
