Whenever I'm in theatre situations I will go out of my way not to talk about my father but in the film world I can be really proud of my family and say 'You know what: my dad's a really really famous theatre director ' because nobody has any idea.
I just hope that I continue to keep a line between my private life and who I play even if they are closely intertwined and so I'm careful. I don't even know where my line is but I know I have a line.
