We just got a better look at HBO’s upcoming epic medieval series Game of Thrones with an all-new trailer. Now the cable network has now released a 10-minute behind the scenes featurette that really digs into the story, characters and all the work that’s going in this adaptation of George R.R. Martin’s fantasy novel series A Song of Ice and Fire. Interviews with cast members like Sean Bean and Peter Dinklage, as well as the book’s author himself, and the sight of sword fighting, jousting and a truly promising production just get me excited even more for the series premiere in 2011. Check out the great featurette after the jump!
