You know, about casting...for some reason I kept picturing the actor who plays Joran Mormont, Iain Gloin as Ser Davos when I read the books. I remember someone once saying that if they re-did Shogun, Gloin would be great for the lead role.
It's "Glen", he's not a Tolkien dwarf.
But I always picture Iain Glen as the perfect middle-aged Obi-Wan Kenobi. He sounds so much like Alec Guinness.
