Gwendoline Christie was filmed with a real bear.
The episode where Brienne of Tarth meets a bear is not a result of computer graphics. Accordingto the actress, the bear, whose name is Bart Junior, is an experienced actor. He had already acted in several other projects before playing in Game of Thrones.
While filming the episode, the actress was protected from the bear by a low electric fence. During breaks, the bear was fed cream from a pan with a long handle so that it “didn’t eat the actress” (that’s how the set team would joke around). “Why do you think I look so scared?” Christie says, recalling her experience.
Lena Headey struggled with the audience’s hatred.
According to the woman who plays Cersei Lannister, the audience hated her character so much that they started to transmit their negative feelings to her as well.
For example, the nurse who was helping her with breastfeeding her second kid would say, “Shame on you!” when recalling the episode of public denudation. However, Headey takes it as a compliment to her acting skills.
