Saying goodbye to Jon Snow was easier said than done for the actor.

Saying goodbye to Jon Snow was easier said than done for Kit Harington

The 32-year-old actor appears on Friday's episode of The Graham Norton Show, and during his sit-down, he reveals that after his final day playing Jon on Game of Thrones, he unexpectedly "broke down and cried" to a random fan on the street. 

"I was determined to be cool about the end and decided that when people came up to me and said, 'Are you Jon Snow?' that I would say very calmly, 'I used to be,'" he says of his plans for fan interactions after wrapping season eight of the HBO series. Things, however, didn't go that way. 

"When I left the set for the final time, I was very emotional, and when a girl came up to me and asked the inevitable question, I broke down and cried, 'I used to be!' Harington confesses. "She backed off pretty quickly!"

While Sophie Turner told ET that she spilled details on GoT's final season to her fiance, Joe Jonas, making him sign an NDA, Harrington reveals to Norton that he told his friend James -- who couldn't have been less enthused with the information. 

"The intensity of finishing something like this and not being able to tell anybody is so hard. It got too much, so I've told one person, my friend James, who doesn't watch the show and fell asleep in the first episode of the very first season," he says. "I knew then that he was zero interested in what I do. We were having a drink the other night and I told him everything about how the series ends, and he couldn't have looked less interested if he tried!"

Harington's wife, Rose Leslie, whom he met on set of Thrones, also knows a bit about how the show's finale will go down. ET spoke with Harington on the red carpet at the Game of Thrones finale last week, where he opened up about how the series has been a huge part of their relationship. 

"I said to Rose the other night, I was like, 'We've been tethered by this show, a long time we've loved it,'" he said "And now we get to enjoy the final hurrah." 

Season eight of Game of Thrones premieres Sunday at 9 p.m. ET/PT on HBO -- and ET will be live blogging along the way. See more on the series in the video below.
