The Game of Thrones star has booked a gig on the third season of HBO’s financial drama Industry as Henry Muck, the founder and CEO of a green tech company that is going public. Harington joins the show as a fan of the first two seasons, telling The Hollywood Reporter at the New York premiere on Monday, “It was fun coming on board something that you’ve seen, that you enjoy, that you’re a fan of. I’d not done that before and it’s a bit geeky. You step into a world that you know and you’re like, ‘Ooh, I’m excited to be here.'”

He also takes on a darker, more complicated character in the series, a departure from what he is best known for after eight seasons as Jon Snow.

“I think there will be no doubt in the audience’s mind that Henry Muck is not morally just at all, he really isn’t. The question is whether they like him, whether they care for him, whether they care about him, and understand that those shaky moral foundations have arrived for a reason,” Harington explained. “And that’s the aim. Jon Snow was wonderful, I loved him, but he was sometimes tricky to play because he was morally kind of perfect, which is difficult to play sometimes.”

He joins the cast that includes Marisa Abela, Myha’la, Harry Lawtey, Ken Leung and David Jonsson, as his co-stars sang his praises on the carpet.

“He’s a brilliant actor and what he brought to Henry Muck — I saw that character in a completely different way,” Abela said. “It was so fun for us to sort of play that relationship out together, but he’s also just a really nice guy, really nice. And when you’re working on a TV show for six months it’s important that everyone is nice.”

Added Myha’la, “It was such a huge compliment that he came in saying, ‘I’m a fan,’ you know what I mean. Someone whose career you respect, whose work you respect, saying, ‘I respect yours too’ is a massive compliment.”

Industry season three premieres on Sunday.
