The Marvel Cinematic Universe is entering its sixth phase, and one of the most critical films in this chapter will be Avengers: Doomsday. During a nearly five-and-a-half-hour livestream, Marvel announced the blockbuster’s cast – and there was no shortage of genuine surprises.

Rebecca Romijn, 52, will officially return as Mystique. She starred as the shapeshifter in “X-Men, X2: X-Men United,” “X-Men: The Last Stand” and “X-Men: First Class and Joan in The Punisher.”
