A new video teases a battle in “Game of Thrones” Season 6 and also reveals how the makeup and prosthetics of some of the characters are created. Perhaps the most difficult look to achieve is that of the Night's King and the other White Walkers.

A new video posted on the YouTube channel of the TV series shows prosthetics designer Barrie Gower explaining how he and his team achieve the look seen on screen. From sculpting to mould makers to people who sew artificial hair onto the silicon rubber mask, the whole process takes about 15 to 20 people.

It takes about four weeks for the team to get the prosthetics ready for one character. Once the masks are ready, it takes two to five people two to three hours to get them on the actors. Then the makeup crew takes over to make sure they appear as per the director’s expectation.

The actors have to spend five to six hours in the chair to go through the whole process. While most of the footage in the video appears to be from the previous season, Watchers on the Wall notes that the scene around the 1:20 mark appears to be from “Game of Thrones” Season 6.

The trailers of the next season tease a major battle in Westeros and it now appears as though the White Walkers will also be involved in a battle of their own. It is not yet clear which army the White Walkers and their army of the dead will be facing in the next season.

With Westeros in chaos, it is the right time for the White Walkers to invade in “Game of Thrones” Season 6. The next season is set to premiere on April 24 and is one of the most highly anticipated seasons of the TV series.
