Casting so far has brought me nothing but joy-- Sean Bean and Peter Dinklage are the only ones listed who are familiar to me, but they're both perfect for their characters and for the most part I'd rather see everyone played by no-names anyway.

And now I just want to go on record saying that if any of these three do end up being correct guesses, Boreanaz should be Benjen Stark, Marsters should be Jaime Lannister, and Glau should be Daenerys Targaryen. I wouldn't object to them in other roles, but I'd be skeptical.
Seriously, someone else should read these books and then we can gush at each other about it for the next year. The only other work of fiction I've ever been so obsessed with is...Buffyverse. And Ice and Fire came first.
Eddard Stark is being played by freaking Boromir, guys. Tyrion Lannister is Trumpkin. BELIEEEEEVE.
