Imelda Staunton as Queen Elizabeth II
Staunton will succeed Olivia Colman's Queen Elizabeth II for the final season. "I have loved watching The Crown from the very start," Staunton said in a February statement. "As an actor, it was a joy to see how both Claire Foy and Olivia Colman brought something special and unique to Peter Morgan's scripts. I am genuinely honored to be joining such an exceptional creative team and to be taking The Crown to its conclusion."
