The idea for the video was originally thought of by BuzzFeed and pitched to the stars by PopSugar.

Stars taking part include Jamie Lannister actor Nikolaj Coster-Waldau, Queen of Dragons Emilia Clarke and Bran Stark’s Isaac Hempstead Wright.

Highlights include clips of all your favourite Westeros heartthrobs, Jon Snow, played by Kit Harrington, to everybody’s favourite horse lord Khal Drogo played by Jason Momoa.

The latest series of the show will be the first to overtake the books it is based on, written by George R. R. Martin.

Fans are especially excited for the upcoming run, as many are keen to find out the fate of Harrington’s Snow – who was left bleeding to death at the end of season 5 – including the wife of the show’s writer David Benioff.

Actress Amanda Peet recently revealed her veiled threat to her husband after learning something bad had happened to the leader of the Night’s Watch.

She explained that she watches the show with the wife of co-creator DB Weiss, Andrea Troyer and the pair were unhappy to find out the fate of their favourite character.

“[When I watched the episode] first I called Andrea, and we basically staged an intervention with them.
