Gwendoline Christie, star of the critically acclaimed HBO series Game of Thrones has just replaced actress Lily Rabe (American Horror Story) for the part of Lyme, one of the leaders for District 13. Rabe was previously cast for the part of Commander Lyme, but had to back out due to a problem with the schedule in filming another movie, Much Ado About Nothing at Shakespeare in the Park.
In Game of Thrones, Gwendoline Christie plays Brienne of Tarth, a former member of King Renly's Kingsguard who was tasked to deliver Jaime Lannister back to King's Landing. I'm not going to bore you with the details, but all you should know is that she is a fierce and formidable warrior who is as tough as any other man. Surely the same qualities that her character Mockingjay would need.
In the novel Mockingjay, Commander Lyme was a former victor in one of the previous Hunger Games. She currently serves as a commander for District 13, home to the rebels opposing the Capitol.
Katniss said that Lyme was middle-aged, over 6 feet tall, and very muscular. Her face was described as unforgettable, as it made Katniss remember her from a past Hunger Games.
Sounds like the description of how Christie's character in [Game of Thrones](movie:817617) looks like.
