D.B. Weiss: It became very clear very early on that Alfie Allen’s performance as Theon Greyjoy in season two was going to be a standout (…) but he was still worried about the state of his role. Would he be coming back in season three? He wasn’t in book three. Were we just going to kill him? We didn’t say. Eventually, we sent him this scene:
David Benioff: We didn’t hear from Alfie for two weeks. Finally, we called him. (…) We asked him if he’d consider coming back as a zombie, which sometimes happens to people in this show. After a long silence on the line, he said he’d consider it. “It would mean having no dialogue and being naked most of the time,” we said, “but it would still be acting.”
He drew the line at naked zombie.
