Yes, the role of Daenerys Targaryen in the HBO series of GAME OF THRONES has been recast.
Our new Daenerys is a beautiful and talented young actress named Emilia Clarke, a recent graduate of Drama Centre London. You can learn more about her here:
I haven't had the chance to meet Emilia yet, but I've seen her auditions. She gave some kickass readings, winning out over some amazing competition from all around the world. She should make a great Dany.
(None of which should be taken in any way as a slight against Tamzin Merchant, another wonderful young actress. Her perfomance as Dany in the pilot was wonderful, I thought).
