To have been chosen when you're in your thirties to play someone who's 120, and then to find when you were in your early fifties you were going to play the same character at your then-age, that is, in your early fifties, in fact I don't think I've come out of the trauma. But the interesting think about that it's an absolutely unique challenge for an actor; I can't think of anyone who's been asked to do that, or indeed been given the opportunity, and I'll always be grateful for that.
