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?"

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.

I think Jesus was a bit more of a fun guy. I'd like to play Him like maybe some days He doesn't fancy it, being God. Some days He's miracled-out and just wants to go have a smoke.

In Wales, singing and storytelling are party skills, not professions.

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. To learn humility, to learn bravery and to remind yourself that the pistons that drive your craft are working on full power. And to remind yourself how badly paid actors can be.

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.

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.
