Game of Thrones: Another interesting Medieval TV series

As if I had enough watching medieval shows like Spartacus: Blood and Sands, another medieval themed series has just premiere on HBO entitled Game of Thrones. 

Game of Thrones is an American medieval fantasy television series created by David Benioff and Dan Weiss for HBO. The series, based on author George R. R. Martin's best-selling A Song of Ice and Fire series of novels, chronicles the violent dynastic struggles among noble families for control of the Iron Throne of Westeros. - source: wikipedia.

The series cast includes notable actors like Sean Bean (notable for his role as Boromir on the Lord of the Rings trilogy series) and Lena Headey (notable for her role as the Queen of Sparta in critically acclaimed movie "300").
