I definitely consider myself a Method actor, because of my training. I might dispute what people consider a Method actor to be. For my money, a Method actor is an actor who has a technique. That has a method. And not one method, but whatever might be required. So a Method actor is always learning.

An actor has to be very, very careful, as one of the most wonderful props - and actors love props - is a cigarette. There's so much to do with it: you can bring it up to your face, play with the smoke. It's just the greatest - ever since I was 16 and in acting school in England, I've been playing around with cigarettes.

I have been known for almost 30 years to sort of do whatever comes my way. It's always been touch-and-go after each job finishes. I just like to be working.
