I remember watching Robert Powell many years ago. He did 'Jesus of Nazareth,' and I remember thinking that was probably my favorite. Once I got the role, I didn't want to watch anything, because it only influences what you do.

Everyone thinks they know Jesus because they've got a personal relationship with him.

I wanted Jesus in 'A.D.' to be very, very, very human - to have those qualities of vulnerability and doubt and pain and sadness and loneliness. Once the resurrection happens and we see that Jesus has risen, it's almost complete, right? It's all about the joy and the smile and the happiness and the closeness to the disciples.

I got the call to play Tony Manero in 'Saturday Night Fever' in Madrid, a role I'd always wanted, as it's such a well-constructed show, and my background is in musical theatre. I'd been travelling back and forth between London and Spain for auditions and had been borrowing money from friends to do it.

For 'A.D.,' when I got the script, I was really moved, because even though it told a story that I knew all my life, it was told in a different way. It was told from a very personal point of view.

The stage is that immediate rush of energy you get from the audience. Also, doing something in chronology - something that starts and finishes the same night. In television, you work toward the one scene, you shoot it, and then you have to forget about it because you have to worry about the next scene.
