Ad For Season 2 Finale of Game of Thrones

The trailer for this Sunday's final episode of Season 2 of HBO's Game of Thrones, the brilliant television adaptation of George R.R. Martin's A Song of Ice and Fire books has been released. The episode will apparently be 10 minutes longer than the usual episode, clocking in at 64 minutes. Season 2 is based on the second book in the series, A Clash of Kings.

Season 3 of the award-winning television series (which has already been approved by HBO for Spring 2013) will be based on the first half of the 3rd book in the series, A Storm of Swords. That book has some of the most controversial scenes in the entire epic series and is considered by some the best book in the entire 5 books published so far. The series is allegedly intended to encompass 7 books, with Book 6 (The Winds of Winter) and Book 7 (A Dream of Spring) forthcoming.
