Fans wondering how the creators behind HBO's Game of Thrones give the show its epic scale need wonder no longer. This behind-the-scenes video details the rugged location shooting that took place in Iceland for season two, and how the producers wanted to limit the use of CGI in order to give each episode a more realistic feel.

This practical way of shooting is a lost art in an age filled with digital landscapes that are often cold and emotionless. To see the care that goes into every episode is just one of the reasons why Game of Thrones was such a rousing success during its first season.

We can't wait to see the snow-capped mountains North of the Wall when Game of Thrones returns for its second season on April 1. Also, be sure to check out the brand-new teaser poster for the show below.
