HBO Debuts Behind-The-Scenes Preview Of <i>Game Of Thrones</i>

Before last night's season finale of Boardwalk Empire, HBO debuted a stunning 10-minute look behind the scenes of Game of Thrones, its upcoming adaptation of George R.R. Martin's bestselling fantasy epic A Song of Ice and Fire.

If even after the trailers fans had reservations about the television series' ability to capture the enormity of the novels, set primarily on the mythical medieval continent of Westeros, this video should put them to rest. The locations, sets and costumes are pretty amazing.

Martin's planned seven-book saga chronicles seven kingdoms threatened torn apart by a dynastic civil war, a threat of invasion by a supernatural menace from the north, and the impending return of the rightful heir to the Iron Throne.

Premiering in April, Game of Thrones boasts a sprawling cast that includes Sean Bean, Mark Addy, Peter Dinklage, Aidan Gillen and Lena Headey.
