I'd just like to share a story of how amazing Charles Dance is.
My brother and I were rewatching an episode about a week ago (think it was "Garden of Bones"), but not giving it our full attention. Making some chit-chat, talking about the show and the books, making some comments and jokes, the usual stuff. The upshot is, we weren't all there in what was happening on screen at the moment.
Then Tywin rode in.
My brother and I both sorta hesitated in our conversation, just stumbling a little bit, our subconscious trying to get us to stop talking.
Then Tywin spoke.We both instantly shut up, our full attention towards the screen, rapt on this man and his charisma, afraid of what he might do if he caught us ignoring him.
