Game of Thrones - The Serus

"This is why I love Game of Thrones. It's like you can do stuff like that and it's Game of Thrones," says HBO executive producer David Benioff. "You really don't need the dramatic buildup to it at all", he adds about Viserys' head coming off in this week's episode. 'It still makes me smile,' added Benioff, who has been a fan for years.
