Now don't get too excited, they aren't releasing new episodes into theaters. However, they are releasing the last 2 episodes of season 4 plus the trailer for season 5. The episodes will be in 150 IMAX theaters for one week beginning January 23. This means we will see "The Watchers on the Wall" as well as "The Children." There are some awesome events in these episodes and some of the best scenes in the North. Wildling attacks, giants, mammoths, a direwolf, "The Watchers on the Wall" is an action packed episode with a lot of fun. "The Children" shows some of the aftermath of the battle as well as Bran getting involved in a battle. We also get a some great scenes across Westeros with Arya, The Hound, and the crew in King's Landing.
There isn't much known about the trailer for season 5. In fact HBO hasn't shown us any new footage yet. Going to the theater is going to be your best bet. There aren't any good movies coming out that weekend so go watch some Thrones!
