The 27-year-old actor plays Jon Snow in Game of Thrones and although he adores working on the show, he is worried about what impact that might have on his future performances.
He said: "'Game Of Thrones' is my life, it's my day job, I love it,' he said, adding, 'But honestly, if there is a curse of Thrones, it's a lifetime of having to talk about it."
Kit got the part as Jon Snow not long after he left drama school and he says that he would be a foolish man if he were to wish away the opporutnity.
He said: "It would be foolish to say I wish I'd gone through a period of longing. Because any actors going through a period of longing themselves would tear my f***ing face off."
Kit is not allowed to cut his curly hair while filming and it gets him noticed more than any other cast member.
He said: "I'm more recognisable in public than much better-known actors. So many people watch, and I go around looking like my character."
Game of Thrones has opened other opportunites for Kit, in such as, 'Pompeii', 'Testament of Youth' and 'Seventh Son' but he hasn't been completely satisfied with all his work.
He admitted to the new issue of Britain's GQ magazine: "I won't name names and I won't name films but I've sat through private screenings, nearly in tears. Hating it. Thinking; this is the end, everything's over."
