As we mature and grow older we collect a lot of baggage, and a lot of that stuff you collect on life's journey gets in the way of acting. My kids can imagine a character and transform in the blink of an eye. It's so simple for kids, so complex for adults.

in the blink of an eye.

Well you just have to own it, I suppose. Own the character, which is difficult.

As you grow older, your music begins to mature and grow older along with you.

I think you have to find the humanity in the character and then the deterioration is a part of the process - the journey of the character. It's like playing King Lear. You can start off as a nice old man who finishes up crazy.

In all honesty, if somebody asked me the secret of auditioning for Americans, I don't know. Often, I do what's called self-taping for America. I go over there quite a lot to sit in a room and do stuff in front of people. You feel like a performing monkey. It's bizarre.
