I listened to the audio version, which was great. It wasn't a full cast, but rather the narrator would change each time the point of view shifted. The book ended and Orson Scott Card had an extra 45 minutes or so of air time discussing how he came up with the story and his life during that time.

I'm definitely going to keep going in the series (darn you Card!). The author noted that he almost thinks #2, Speaker for the Dead, is better than #1.
