My mother wanted me to be a teacher. She had this vision of me walking across the quadrangle in an Oxford college wearing my academic gown.

I don't mind a little Sturm und Drang. When I was doing 'Riding in Cars With Boys ' I wouldn't smile at anybody because my character Bev was angry at the world. I'm the opposite. Inside my head I'd be like God I'll explain to you at the end of shooting that I'm not this person.
