If you're a long-term reader of this blog, you'll know I love these special effects showreels for Game of Thrones. A new one's been released covering the third season's work by SpinVFX, and it's as enlightening and beautiful as ever. I'm amazed by how many shots involve some degree of trickery and digital augmentation, like extending landscapes and sets. This video's a wonderful way to spend four minutes of your day, although I guess you could extrapolate a few spoilers if you haven't seen the third season yet. Fair warning.
