Kit Harington "burst into tears randomly" for a month after he finished filming 'Game of Thrones'.
The 34-year-old actor will always treasure his time as Jon Snow in the HBO drama series but has "no desire" to return to the role, even though it took him a while to adjust once he'd wrapped work on the final season of the show.
He said: "I have no desire to go back and do any more of that show... I have such a fond place I my heart for that show. For a good month afterwards I just burst into tears randomly. I can't think of a better job to have in your 20s then to play Jon Snow."
The final episodes of the programme air next year but Kit hasn't told anyone how the series ends - not even his wife and former co-star Rose Leslie.
Speaking at Esquire Townhouse over the weekend, he admitted: "I chose not to tell [Rose]. It's quite exciting walking around knowing no one knows..for this I was like I'm not telling anyone. I don't think she's guessed it right yet."
The British actor also told an encounter with a surprising fan of the show, Prince Charles' wife Camilla, Duchess of Cornwall.
He said: "I was at Wimbledon once and I was sat at the Royal table and Camilla Parker Bowles turned to me and said, 'So are you dead?' "
Kit recently admitted he doesn't think everyone will be happy with the ending when 'Game of Thrones' draws to a close after eight seasons next year, but he thinks that's always the case with a good drama series.
He said: "I think a TV series that's spanned eight, nine years is an incredibly difficult thing to end. I think not everyone's going to be happy, you know, and you can't please everyone.
"My favourite TV shows are 'Sopranos', 'Breaking Bad', and 'The Wire' and they all ended in a way that...It's never going to satisfy you."
