In a recent interview with a magazine, the actor reminisced how the two fell in love while filming the series. He labelled his time shooting season two in Iceland as ‘his favorite show memory’.

"Because the country is beautiful, because the Northern Lights are magical, and because it was there that I fell in love," Harington said.

"If you are already attracted to someone, and then they play your love interest in the show, it becomes very easy to fall in love," he added.

Meanwhile, during an appearance on The Tonight Show with Jimmy Fallon, the actor spoke about how he revealed Jon Snow’s fate to get out of speeding ticket. The 29-year-old actor was driving back from his parents’ house when he got caught speeding and was offered a chance to get out of it if he revealed the fate of the popular character.

He said, "One policeman knew. He said, ‘Look, you can either follow me back to the police station now and I book you in, or you can tell me whether you live in the next series of 'Game of Thrones'."

When Kit confirmed his character would still be alive, the officer told him ‘On your way Lord Commander. Keep the speed down this far south of the wall.’
