Human beings, we have dark sides; we have dark issues in our lives. To progress anywhere in life, you have to face your demons.

I'd never done anything that required a five-year commitment. To build a show that seems to have kept the imagination of the world so much was a bit otherworldly.

I loved playing Walternate because he was completely the same character, version 1985, and then it developed in such a different way, physically and mentally. So, to be able to play that, in the same television series, as playing the other ones was a fantastic gift for me.

I love having played Walter because I suppose any actor brings a certain aspect of their own personality to their work, and I had a fairly broad canvas to paint on with the different versions.

I would kill to do more work with Orla Brady, I think she's that gifted.

I don't know where the line is. I don't know how much of myself is in Walter. There's got to be a bit of him there.

Many very strong fathers have turned out ineffectual sons by not allowing them to grow as men.
