Winter has come, so there is apparently no natural light in Westeros to illuminate the footage, which is mostly set in caverns, or under cover of darkness. There are some nice images of the dragons, but not much of the Night King and his army of the dead.

A teaser trailer was released in January (see “'Game of Thrones' Trailer and Premiere Date”), and a photo gallery was released last month (see “'Game of Thrones' Season 8 Picture Gallery”).

Game of Thrones, Season 8, the final season, will premiere on Sunday, April 14.
