However, the network may have accidentally leaked the full cast list for the upcoming premiere episode, revealing that a certain main character may be absent.
A listing appeared on the official HBO website last week (and has since been removed) which seemingly confirmed over 30 names for the season eight premiere.
HBO has been remarkably good at keeping information regarding the eighth season of Game of Thrones under wraps.
Game of Thrones returns to HBO and Sky Atlantic for its final season in April.
