Ever wonder how much of Westeros is real-life and how much is CGI and clever hiding of landmarks or just straight up green screen? Well wonder no more, as Mackevision, the people behind Game of Thrones' visual effects, released their making of reel highlighting all the VFX in season 4 that they completed or contributed to and it is seriously impressive.

We don't know what we're more gobsmacked by, the fact that we didn't even question all of this when we're watching the show, or that loads of this is actually Ireland. Are you well Belfast? 'Cause you're looking well.
