A shock series finale saw Snow stabbed multiple times and left in a pool of blood.
During an interview to a Belgium based magazine Humo, Harington clarified his commitment to the show over the coming years.
A Dutch reader wrote out the exchange on Reddit:
Harington: […] I often felt frustrated as well. I had to pass on amazing parts because I was attached to Game of Thrones. So the show is like a double-egded sword to me: I owe a lot to it, but > at the same time it has almost completely drained me. Oh well, I try not to think about it too much. The important thing is that I now know exactly how long I am still under contract, and in the meantime –
Interviewer: How many more seasons would that be?
Harington: Nice try (laughs). I can't talk about that. Let's just say that Game of Thrones will remain a part of my life for a while, I'll probably be in my thirties when it's over. One thing's for sure: the day I'm no longer on Thrones is the day I'll bury myself in movie projects (laughs).
At 28, Harington appears to have confirmed his involvement in at least two more seasons of the show.
However, as fans of the series have pointed out online, this may relate to flashbacks, montages, or other work that won't necessarily render previously accepted outcomes obsolete.
And the real reason Jon Snow appeared to die might actually be a cunning ploy to cut the show's wage bill.
Either way, Harington has definitely been to Belfast and has almost certainly filmed something for the upcoming series.
But it's the how and why that's important, and for that we'll just have to wait...
