Brian Cox thinks Jeremy Strong put himself in a "very, very vulnerable position" with his viral New Yorker profile

He told Deadline: "It was Jeremy's idea, the whole article. He pushed for it, and you know, and people kept warning him about it.

"In a sense, he got hoisted by it, and I think it was unfortunate. I think he should never had gone down that road because playing Kendall has put him in a very vulnerable position."

Brian admitted he worries about the "pain" Jeremy puts himself through to play his troubled on-screen son, Kendall Roy.

He said: "Let me tell you, I have such respect for Jeremy as an actor and I just wish him well. I think he lives in a lot of pain. I mean, he creates the pain in the role he plays. That doesn't necessarily help, but he does... there is a certain amount of pain at the root of Jeremy, and I just feel for that pain.

"I think that he puts himself in vulnerable positions and that New Yorker article, he placed himself in a very, very vulnerable position, and I think that he didn't need to do that."

The veteran actor admitted working with Jeremy can be "exhausting", but the 'Succession' cast are happy to put up with methods because they "love" him and he always gives an "extraordinary" performance.

He said: "He does what he does and he does it brilliantly, but it's also exhausting. Particularly exhausting for him, but it's also exhausting for the rest of us from time to time. But we weather it because we love him and because the result is always extraordinary, what he does, but at the same time, there is the double-edged sword that goes with it."

In the profile, Jeremy - who admitted he doesn't agree that 'Succession' is a dark comedy - insisted he doesn't consider himself to be a method actor but practices what he calls "identity diffusion".

He said: "I can't work in a way that feels like I'm making a television show. I need, for whatever reason, to believe that it's real and commit myself to that sense of belief...

"To me, the stakes are life and death. I take [Kendall] as seriously as I take my own life."

The 42-year-old actor also admitted he had injured his leg on season three and fractured his foot during season one after throwing himself into scenes.
