A special effects trailer for Game of Thrones has made its way to YouTube. And although there are spoilers, we've figured out a way for you to watch it spoiler-free.

Much of the footage we see here is a look into the work done by special-effects wizards BlueBolt. From plain landscapes that morph into ornate vistas with castles, we get to see the reason why Game of Thrones has been nominated for an Emmy for special visual effects.
