The red-headed actress is rumored to be playing the villain in X-Men: Dark Phoenix, which sees Jean Grey aka Phoenix's (Sophie Turner) powers amplified when she comes in contact with a cosmic energy called the Phoenix Force. Chastain -- who tellingly also tagged Simon Kinberg, the film's writer/director, in her post -- will most likely be playing Lilandra, the empress who leads the quest to imprison and execute Dark Phoenix.

The movie would be Chastain's first film since her June wedding to Gian Luca Passi de Preposulo. See more in the video below.
