The joy of a period film is that you're taken to another world. The costumes determine the way you move, and then consequently the way you breathe. And then, the way you breathe effects the way you think.

We're both Welshmen and growing up, when Howard Marks was finally caught, it was all over the news. He did an interview in the Welsh language, which I also speak, and I was sort of just amazed that this man from a small country was for many years supplying much of the world with most of the marijuana it was smoking. It was incredible.

Film and stage are very different; I don't necessarily prefer one over the other. Every few years, I get a big itch to go back to the theater.
