It sounds really corny but every film that you do is its own journey, it's its own experience, it's its own thing. Often you think it's going to be one way and then it goes another way - you think you can chart a character and then other things happen. That's the amazing thing about our jobs, it's constantly changing and it's extremely dynamic and you therefore have to be dynamic as well.
