If the preview released earlier this week for this week's Game of Thrones episode, "The Watchers on the Wall", wasn't enough to satiate your appetite for all things Westeros, then perhaps this extended promo with new footage will be right up your alley. The massive army of Mance Rayder (Ciarán Hinds) gets closer and closer as a full-scale war is about to break out, with Jon Snow (Kit Harington) and the Night's Watch facing their biggest challenge yet in defending the Wall. Check out these new scenes, that include glimpses at the mammoths and Giants in the penultimate Season 4 episode, airing Sunday, June 8 at 9 PM ET on HBO.
