Clint Eastwood is one of the few 'great' directors and actors left in Hollywood. As a director, I think what makes his films so exceptional is that they are so unfussy and understated, and the focus of the film is very much on the narrative. Having learnt his trade on the ground, he knows how to get the best out of the actors he works with, and demonstrates a maturity of judgement that's so rare in modern cinema. In period films such as Changeling, Los Angeles in the 1920s is so wonderfully evoked that once you've taken it in, you can almost forget about it.
