Many of the stars of Game of Thrones grew up on the show, from its premiere in 2011 to its finale in 2019.

Harington even blurts out an involuntary 'f**k off' when confronted with the callow Jon Snow, before covering his face.
Williams watches through her fingers, as her 13-year-old self explains how she's 'best fwends' with Sophie Turner.
“So embarrassing,” she manages as the footage ends.

The reel was filmed for the Game of Thrones: The Complete Collection Blu-ray set, which will be coming soon from HBO.
And it's probably worth the entry price for Harington's cringing alone.
