Location manager Robert Boake breaks down the Belfast, Ireland portion of production in a new featurette for Season 4 of Game of Thrones. The crew member explains how streamlined the shooting has been this year, as opposed to the production being a "travelling circus" in previous seasons. We also hear from producer Chris Newman along with stars Iwan Rheon (Ramsay Snow), John Bradley (Samwell Tarly), Owen Teale (Alliser Thorne) and Rose Leslie (Ygritte), who talk about the importance of shooting on location, instead of on a backlot. Take a look at this new behind-the-scenes footage before Season 4 debuts Sunday, April 6 at 9 PM ET with "Two Swords".
