The actor, who played Jon Snow for all eight seasons, said that there were plenty of things he found “horrific” about being on the show, including filming the dragon sequences.
“Emilia [Clarke, who played Daenerys] had been moaning about it for seasons, and I was like, ‘Yeah, yeah, yeah. Whatever. You have not been through the mud in Northern Ireland. A buck in a nice warm room?’,”he told The Hollywood Reporter, referencing the rig they used to film the dragon-riding scenes.
“But she was absolutely right. It was horrific. It’s not acting at all. It is not acting, it never will be acting, and it is not what I’d signed up for. It is very uncomfortable as a man.”
Harington, who has been nominated for Best Actor at this year’s Emmy Awards, also said he “hated” filming the final season’s big battle episode, but added that he has a different perspective looking back on it.
“As tough as it was, it was Thrones, man. It was Thrones! It was everything Thrones should have been. It’s a full set built, hundreds of extras throwing everything they had into it, all of us as a big ensemble cast – I loved it.”
Harington’s former co-star Richard Madden (Bodyguard) recently revealed why he was “thankful” to be killed off in the show’s early days.
In a new interview, author George RR Martin admitted that the series held him back from completing work on his final two books.
