What did you make of how these two actresses embodied those characters? I have to give an immense amount of credit to our casting director, Nina Gold. The casting of Arya was particularly difficult, as I somewhat feared it would be; I think we looked at more potential Aryas than any other role in this show. I wasn’t physically present at the casting — I was back here in New Mexico working on the next book — but I was linked into it on the internet. So they would videotape these girls … I think we probably saw like a hundred girls. And at a certain point in the process I was really beginning to say, “This is a disaster, we can’t find anyone here.” These are not parts that require the girls to be cute, and deliver clever little one-liners to put down their idiot father, like you do in a sitcom. These are girls that are gonna go through really huge personal traumas. They’re gonna see death and war. They’re gonna see people close to them beheaded.
