To be an artist, you don't have to compose music or paint or be in the movies or write books. It's just a way of living. It has to do with paying attention, remembering, filtering what you see and answering back, participating in life.
Be kind. It's worthwhile to make an effort to learn about other people and figure out what you might have in common with them.
People will like to say that 'Eastern Promises' is brutal, but the only reason they say that is because the scenes stick with them. They are realistic. They are in-your-face and you see the consequences. It's not a bunch of quick editing cuts.
