I do the best I can - I know my way around [Russian method acting pioneer] Stanislavski, but I can't take myself seriously like that. I respect people who do it, of course. I just think I'm lucky to still be working at 73. You reach a point in life where you just think, "Show up, do your job, make sure the cheque's on the way," and that's it. I'm not hungry to do anything more, really.

I love to read, and so I've been reading everything I can, not intensely, but I love to read so I read "Origin of Species" by Darwin and I can't make head or tail of E=MC squared by Einstein, but I try to baffle my way through that.

When you begin to believe you have license because you are a special person breathing special oxygen, that's when you're in big trouble. That's the road to insanity.

As a Welshman that can't sing, I never feel more proud to be Welsh than when I hear the Treorchy Male Choir - the Master Choir of them all. If I could sing I would apply for membership myself.

People ask me how did you choose the part and how did you prepare for this work? I just learned the lines and showed up; I don't know what else to say because that's all I know how to do.
