Bad news. Westeros isn’t real. So how does Game of Thrones make it look so believable? For that, fans can thank the magic of visual effects and CGI. Emmy-winning VFX team Rodeo FX shows exactly what brings the show to CGI life in a video that strips down the stunning visuals of Season 4. The video is similar to another clip released by VFX studio Mackevision last month. Special effects are coming.
