Mark Bonnar says his career represents "little steps on the way to death".
The 49-year-old actor has starred in a number of successful series during his career, including "Catastrophe" and "Line of Duty", but Mark tries to keep his profession in some sort of perspective.
Asked how he views his career, he explained: "Little steps on the way to death. Hopefully each of those steps is nice, intricately crafted little something to look at, to observe and to feel something for."
Despite his career success, Mark feels he's remained unaffected by fame.
The Edinburgh-born star explained that he's retained a working class mentality, in spite of where his career has taken him.
He told Radio Times magazine: "I always considered myself working class, because I was brought up on a council estate.
"I still do, really. I mean, I might have a bit more money than I did then, but it's in your head, class, I think. It's how you feel in there."
Mark also revealed he is happy to listen to job offers from all comers, insisting he doesn't just consider himself to be leading-man material.
He confessed: "I've no idea what that means. It's all well and good thinking of yourself in one way. Then you wake up in the morning and go, "Right. How am I going to pay the mortgage this month?"
"There's a balance to be struck, always. But I think that the choice we have - the one choice we have as actors - is to say no. And it's about doing that well, making the right choice."
