Game of Thrones cast scream when they see what Kit Harington looked like in season one

Mortified actor is heard shouting 'f*** off' as footage of him as a teenager in season one flashes across the screen

The cast of Game of Thrones were forced to watch footage of themselves from a decade ago during a reunion special hosted by Conan O’Brien.

The segment is an endearing reminder of why fans fell in love with the show, thanks to the strong chemistry of its lead cast.

Co-stars Kit Harington, Sophie Turner, Maisie Williams and Isaac Hempstead Wright, who played the Stark family on the hit HBO show, watched the footage back for the first time, with plenty of hilarious reactions.

“It’s so embarrassing,” Williams commented.

She probably felt better after the reactions to Harington, however, who was shown clean-shaven and speaking enthusiastically about getting to wear a big cloak and carry a sword.

Williams screams as the footage of him appears on the screen, and the present-day, mortified Harington is heard shouting in shock: “F*** off.”

In another moment, a young Turner speaks about her growing friendship with Williams. “I think we’re going to be friends for a long time,” she says.
