Kit Harington has been quizzed endlessly about the fate of his Game of Thrones character Jon Snow - but it stepped up a gear on the Jonathan Ross show when he underwent a lie detector test.
Long-standing character Jon was brutally stabbed and left dying in the snow at the end of the fifth series.
Despite the death scene, Harington has repeatedly been forced to quash rumours that Jon could secretly be alive and ready for a comeback.
Even the Duchess of Cornwall is keen to find out whether Kit Harington's Game Of Thrones character Jon Snow is truly dead, the actor has revealed.
But on Saturday night, to prove once and for all that his character is dead, Harington was strapped into an electric shock device.
Asked on the Jonathan Ross Show about whether his character is really deceased, the heartthrob actor said: "I get this from everybody.
"Me and my brother got invited to Wimbledon, as you do, and a Royal was hosting, we didn't know which Royal it was, and it was the Duchess of Cornwall and she was hosting it.
"And we got sat with her, me and my brother , and she leant over the table and said 'Are you dead?'
"No word of a lie."
Harington, 29, was spotted filming in Belfast as Jon Snow recently, further fuelling the rumours.
But he told Jonathan Ross: "I was playing a corpse. I was there for a little bit, I was there for about a month or two months, it was spread over a bit and I was playing a corpse."
Questioned further about how filming corpse scenes could take so long, he said: "I won't tell you how many episodes I'm lying dead but it's enough that I was out there for quite a while.
"It's going to be so satisfying when you see it and you realise that I was telling the truth the whole time."
The actor will soon take to the stage in Doctor Faustus at London's Duke of York Theatre.
