Whenever you're doing film for television and you look at the budget that you have, which is much more constricted than a movie budget, you think, "God, are they going to be able to do what they say they are?"

I've been to unpretty places with the roles I've played, and I'm attracted to reckless abandon. I like being taken to the edge of my own abyss.

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.

When Howard Marks came out of prison, years later, I met him at a concert in South Wales; I was a young whippersnapper and Howard was kind of an outlaw hero. I said to him - and it's on tape, a cousin of his filmed our meeting - I said, "If you write a book, I want to play you in a movie." He said, "Let's shake on it," and we did. Thirteen years later, there we were, making the movie.

It is joyous for any actor to enter other grounds of consciousness and thought. At the end of the day, we just all like dressing up and playing around.

If I'd been a rock star, I'd probably now be dead.

I'm interested in playing Rasputin at some point. I find him such a fascinating character and a fascinating period in Russian history. Either Rasputin or Jesus. I think I have more of a chance to play Rasputin.
