Continuity on the Game of Thrones set made a mug of themselves, when a modern day to-go coffee cup was left in shot, by mistake, during filming of episode four of the final series.

An eagle-eyed US comedian Zane Hijazi spotted the modern day cup, sharing the blooper on Twitter.


It was pictured in shot when Tormund Giantsbane raised a toast to his friend Jon Snow for his success with the Night King.
