Game Of Thrones Season 6 Featurette Hints At White Walker Threat

HBO has released a behind-the-scenes featurette for Game of Thrones Season 6.

The featurette focuses on the series' prosthetics, showing how some of the creatures of the world of Westeros – primarily White Walkers, but Giants and Stone Men as well – are created.

As far as hints at things to come go, the featurette shows the Night King and other White Walkers leading a large group of wights. Could a full-scale invasion be on the horizon?

Game of Thrones Season 6 premiers on HBO on April 24.
