On-screen personalities may appear larger in reel life but might actually be short in real life. Kit 'Jon Snow'
Harrington is case in point. At 5'8'' the actor is shorter than some of his cast mates including Sophie Turner who is 5'9''. So Kit was made to wear high heels to appear taller and look more imposing.
Kit revealed this fact in an interview with Esquire magazine. During a conversation about his understandably heavy costume, which includes a sword and a large fur coat, Kit said, "I was in high heels, because I'm short and they need me to look taller than other people, so I'm carrying fifty pounds in high heels.
You'd have about a week or two where your body went into shock, going, 'I can't, I'm knackered." Kit's co-star and current love interest in GoT Emilia Clark has also commented in interviews that she gets rude
comments from fans who meet her in person as they assume that she is taller than her 5'2'' frame.
