In a post on his Not A Blog, George R. R. Martin provides a short update on the progress of season three.
I finished and delivered my script for season three of GAME OF THRONES. It’s episode 307, with the working title “Autumn Storms.” David and Dan seem to like it. Casting is in full swing for the new season, so I’m watching auditions every night. Froggy may be turning up soon, but don’t hold your breath. I’m too busy to devote much time to whipping up obscure clues.
Winter Is Coming: It seems like most, if not all, the scripts for season three have been finished. And now we have official confirmation of casting being underway. It sounds like they may even be close on a few roles. Can’t wait until those casting announcements start rolling in!
