I have a very healthy relationship to my work, and I find that if a scene is working, no matter how intense it is, you have the catharsis on screen, and you can let it go. I think it's, if at the end of the day you feel like you haven't cracked it, that's when you go home and it's more difficult to switch off.
I've got a funny old face. Someone described it once, and I think they were being kind, as character. But I know what they mean! I've never been that conventional. I suppose maybe it means that my face can look different in different lights, so I just try and sort of keep it simple when I'm going out, to still look like me.
