HBO has unveiled yet another behind-the-scenes featurette for Game of Thrones, returning Sunday, March 31 at 9 PM ET with the Season 3 Premiere. This video takes us to frigid Iceland, where they are shooting Season 3 scenes that are set "beyond the wall," home to Mance Rayder (Ciarán Hinds). Series creators D.B. Weiss and David Benioff speak about how this truly frigid country makes all the difference in capturing the essence of this land north of Westeros. Take a look at this new video to explore the harsh conditions the cast and crew members must endure this season, which includes interviews with cast members Ciarán Hinds, Rose Leslie (Ygritte), Kristofer Hivju (Tormund Giantsbane), Mackenzie Crook (Orell), and Kit Harington (Jon Snow).
