The monumental war scene took a monster three months to shoot - over 50 days - with the majority of the filming taking place at night.

Discussing his experience he told us: "It was occasionally miserable but I had never done anything like it and I might never do anything like that ever again in my life.

"Some of the set pieces are some of the most impressive stuff ever seen or that has been seen on television before and like it was real, there was real stuff there, real tactile things that you could interact with.

"There was a day where like there were a lot of people running around and were given weapons to run around and it was genuinely scary.

"People running past you knocking you with shields and swords and it's like, well okay."

The episode, which is directed by Englishman Miguel Sapochnik, took a total of 11 weeks of night shoots in freezing temperatures with only trailers and space heaters to provide amenity.

Joe added: "There were times when you could look around and not see anything, like not see a camera or anything and any sort of evidence of the world.

"There were nights that were miserable but there were so many moments where you could turn to the actor next to you and say, and probably for the first and only time in my career, that you were being made part of TV history.

"And we're in it, we're stood in the middle of it, it's amazing."

Jacob and Joe smile on the red carpet

Joe's character Gendry has one of the most fascinating character arcs in the entire series.

Introduced as a menial blacksmith with little self-worth, he soon learns he is the bastard of King Robert Baratheon and the last living person of House Baratheon's bloodline - giving him a legitimate claim to the Iron Throne.

Commenting on Gendry's unique development Joe said: ""I think he's had a perfect arc, it's been a constant voyage of discovery. Imagine not knowing anything about where you're from and then finding your place within this world.

"That's what's he's been striving for the whole time, looking for purpose. I think in learning about his parentage it's somehow, although neither of his parents are around, it gives him that grounding and he's found his calling.

"I think this impending reckoning doesn't mean he's not terrified but I think it's what he's been searching for his whole life."
