‘Game of Thrones’ VFX Reel Brings Westeros to Life (Video)

Visual effects are added to real locations in Ireland, Croatia and Iceland

The geography in “Game of Thrones” is sprawling and diverse, so it's not a surprise that HBO needs a little movie magic help in recreating the exact universe George RR Martin created in his book.

A new visual effects reel has been released from Rodeo FX, the company that worked on the show's fourth season. The reel shows off a before-and-after look at how the show's elaborate production design come together.

A lot is green screened and added in post, but perhaps the most surprising revelation to come out of the reel is just how many of the show's sprawling set pieces are rooted in reality.

The majority of the epic settings revolve around the massive armies and exotic locales which surrounded Emilia Clarke‘s Daenerys Targaryen, as she stands and gazes over the lands she hopes to rule over one day.

The more fantastical or dangerous elements are added later, but, as the reel shows, plenty of beautiful scenery is already present in the locations on which the show is shot, with visual effects used to amplify what's already there.

“Game of Thrones” is now shooting its fifth season, with parts filming in Spain.
