There’s a new post at HBO’s official Making Game of Thrones production blog, written by writer and producers’ assistant Bryan Cogman. In it, he describes being at the location which represents Winterfell—probably Castle Ward—and watching Isaac Hempstead-Wright as Bran.
And then… there’s more, as they link to backdated entries from earlier in the shoot. Fascinating material, stretching over many weeks! For example, in this post from the first day of shooting (July 23rd), he says that Cersei and Ned are having a juicy scene which is not from the books. I suspect this would be a scene in King’s Landing from other things we have heard about the early part of the production. And then after that, a scene from his own episode, episode 4. He notes that most filming in the first weeks was at the Paint Hall and the Red Keep sets there.
There’s really too much to digest right off, so go ahead and read it yourself. The dispatches run through August 5th. Our thoughts on what it says about the production schedule will come later.
