Oh, and re: your HP discussion I thought you might enjoy reading this from a set visit to the Colbert Report yesterday:

I guess they usually chat a little bit first to make sure the connection's good, and Jon started out by saying, "Stephen, how's the little girl?" And Stephen said, "Oh, she's okay." And then he turned to us and told us that his daughter had been in the hospital all weekend. So Jon was asking how she was, and Stephen said she was doing better, and home, and the antibiotics had worked... Stephen said, "All she wanted for this weekend was to lie in bed and read Harry Potter without her brothers bothering her. So I told her that she was getting that, only every once in awhile someone would come in and jab her with a needle." And we laughed, and then Stephen said, "VOLDEMORT!" and made a stabbing motion.
