Helen McCrory (The Last of the Haussmans) returns to the National Theatre to take the title role in Euripides’ powerful tragedy, in a new version by Ben Power, directed by Carrie Cracknell. Medea is a wife and a mother. For the sake of her husband, Jason, she’s left her home and borne two sons in exile. But when he abandons his family for a new life, Medea faces banishment and separation from her children. Cornered, she begs for one day’s grace. It’s time enough. She exacts an appalling revenge and destroys everything she holds dear. Tickets online at GuildHall.org or at Box Office 3 hours prior to curtain; theatermania.com; or 1.866.811.4111.
