Kit Harington knew he had to 'up his game' when he was 'humiliated' by Bella Ramsey in Game of Thrones scene

Kit Harington knew he had to "up [his] game when he was "humiliated" by Bella Ramsey in a 'Game of Thrones' scene.

The 38-year-old actor felt he had complacent playing Jon Snow after six seasons when his then-11-year-old co-star - who plays Lady Lyanna Mormont - tried to give him a prompt when he'd forgotten a line of dialogue.

In conversation for Interview magazine, Bella said: "I don’t know whether you remember this, but I remember it quite vividly and have some remorse for it now, but during that scene I was mouthing your lines to you.

"Now I’m like, 'Oh my gosh, how awful.' But at the time it came from a very innocent place of being like, 'Kit’s struggling with his line and I know it, so let me just mouth it to him.'

Kit laughed: "I do remember you helping me out and it being quite humiliating. Bet yeah, thanks for that. I’ve probably chosen to forget it."

After Bella noted their behaviour was probably "annoying" her former co-star replied: ""It wasn’t at all. If anything I was like, 'Oh god, I’ve got to up my game. I came here not really being comfortable enough with my lines, in the arrogance of however old I was, thinking I’m just opposite some child. And then that child actor is wiping me off the screen.'

"Not that it’s a competition, but you’re like, 'Oh, I’ve got a bit too comfortable in my Jon Snow-ness.' "
