How hard do you find it playing a character when you don't know his own motives?
Well it is a little bit bewildering but he's such a sardonic personality anyway, which is in the nature of the kind of parts I get to play these days. I just play it straight down the middle. I play each scene for what it's worth.
What do you most like about the character?
I think possibly his sense of humour. A rather nice thing is that the burden of the work is on the shoulders of the younger people. Richard Coyle and Samantha Janus really have to carry the whole series through on their shoulders. I just pop in every now and again with some very funny lines and a lot of sardonic wit to go with it - and go quietly home again. That for me at my age is a great joy.
