Xaro Xhoan Daxos
Casting is underway and we should be hearing who's cast soon since filming on the second season is scheduled to start in July.
Here are the casting calls that have been put out for Melisandre and Brienne:
[MELISANDRE] Age: 25-35. A red priestess from Asshai, a mysterious region in the far east, Melisandre is an influential counselor (and eventual lover) of Stannis Baratheon. She possesses prophetic powers and controls dark forces. Melisandre is highly sensual and seductive and well aware of her sexual command over men. She means to impose her religion on the world by all means necessary. She is extremely dangerous to any who dare stand in her way. Recurring. (Season Two: 5-6 episodes/Season Appearances: Multiple Seasons) *Nudity required*
[BRIENNE TARTH] FEMALE. Age: 20s. A skilled warrior in service to Renly Baratheon. Larger and stronger than most men, we first meet Brienne when she wins a tournament, defeating the famed Loras Tyrell. Big-boned and plain faced, she has an awkward personality, but is also honest and loyal. She is derisively known as “Brienne the Beauty”… RECURRING. (Season Two: 6 episodes/Season Appearances: Multiple Seasons) Must be a MINIMUM of 5’10″. Do NOT submit actresses that look like models. We are looking for a big, WARRIOR-TYPE woman that’s more MANLY than womanly.
