Why did Mance Rayder trust Jon Snow

This time the "Game of Thrones" video blog takes place in Jon Snow's Island setting

Of course, season 3 of game of Thrones back to the icy cold behind the wall, in which John Snow has to fight for his very own development path without familiar role models.

Correspondingly cold, snowy, rough landscapes were found for the popular HBO-Fantasy series based on the George R.R. Martin is based in Iceland. In a new making-of clip of the video blog for season three, Jon Snow actor Kit Harington, Mance Rayder actor CiarĂ¡n Hinds and Ygritte actor Rose Leslie report how excited they are to return to this world in season 3. Newcomer Kristofer Hivjo, actor from Tormund Giantsbane, raves about Iceland as the perfect place for the part behind the wall.

In the video you can see how Iceland's landscape inspired the shooting - and that snow as well as ice in the hair and beards of the actors are real - the freezing and searching for warmth as well, as co-showrunner David Benioff explains. And that by the end of the series you will have spent more money on locations than on VFX.

Besides Iceland has game of Thrones still shooting locations such as Northern Ireland, Croatia, Morocco and meanwhile Los Angeles on his shooting schedule - for the first time actors from the USA were also cast for them. A new real bear for an important scene (book connoisseurs know which ones) has already been cast, if you can call it that.

Season 3 of game of Thrones goes to on March 31st in the US HBO at the start. Shortly before we will be with RTL II from March 8 to 10, season 2 will be broadcast as a TV marathon.
