The Wrap has revealed that Natalie Dormer has joined the cast of The Hunger Games: Mockingjay as 'Cressida'. According to The Hunger Games Wiki, the character, "was told by Plutarch to follow Katniss throughout her journeys in the rebellion so they could make numerous propos across Panem to encourage strength and morale in the rebels." The actress is perhaps best known for playing 'Margaery Tyrell' in Game of Thrones, although she will next be seen in Rush and The Counsellor. She will apparently be featured in both instalments of the two part finale to the franchise. What do you guys think of this latest casting addition? Sound off below!
