Harington played Jon Snow in the fantasy series for five seasons, but his time in the fictional region of Westeros seemed to have come to an end after his character was stabbed and left bleeding on the ground.
Fans began to speculate that Snow did not die in the series five finale after Harington was spotted in Belfast, Northern Ireland, the city where the show is shot, just as filming on season six began in July (15).
The 28-year-old actor has now addressed the rumours and suggested his time on Game of Thrones is not done yet.
He tells Belgian magazine Humo, "The show is like a double-edged 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... Let's just say that Game of Thrones will remain a part of my life for a while, I'll probably be in my 30s when it's over."
