Jerome Flynn felt like he was "selling his soul" when he accepted a role in 'Game of Thrones'.
The 52-year-old actor plays mercenary Bronn in HBO's hit medieval drama - which airs on Sky in the UK and is now shooting its sixth series - but he's admitted he had no idea it was going to be so successful and was even worried it would ruin his career.
He shared: "I walked into one of the most popular shows on the planet. I'd put it in a bracket of American twaddle. I had a picture of dying a terrible death, a selling-my-soul kind of feeling. I'd never done anything American before."
However, the 'Ripper Street' star realised as soon as he met the show's producers and the cast - which includes Kit Harington, Lena Headey, Emilia Clarke and Peter Dinklage - that it was going to be something special.
Jerome added to Radio Times magazine: "I had ideas about how it went that were, of course, very naive. Then when I met the producers, I got an idea of what it meant to them, and the scale of the production. Then the cast turned up, and I realised this was epic. Wonderful to be part of. How did I ever think?"
