That actress playing Brienne is pretty tall. I remember seeing her in heels in Dr Parnassus' Imaginarium. She looked gigantic then too, but hotter.
No they announced awhile back during the casting that the Reeds were not going to be in the show. Bran's companions will be Hodor and Osha. No clue what they intend to do with Rickon.
Episode 3 was great. Good mix of characters and action. Tyrion's "double coin" of Pycelle's whore had me busting up laughing. Dinkledge rocks. Also loved Caetlin's bit of acting with Renly. She's seeming more likable this season. Only little disappointed that Sansa was such a little snot to Shae. This is where I started liking Sansa more in the book. But I suppose it does make sense if they're setting up for certain future events.
