Joseph Fiennes: I could see it in the piles of scripts: I'm not going to get the roles I want, but how do I challenge that? I wanted freedom.
Joseph Fiennes: I've always believed that you shouldn't want to mend a broken heart, because that's someone you don't want to forget. Scars can be good.
Joseph Fiennes: There are great creative choices outside the mainstream. I would like to do more experimental films, rather than Dukes of Hazzard 5.
Joseph Fiennes: I want to have another word for 'costume drama'. I call them 'modern dramas, with tights'.
Joseph Fiennes: While I was training, I spent four years just being a dresser at the National Theatre - picking up smelly pants and socks was a pretty good insight into the 'glamour' of acting. That was how I learned what it was really about.
