“On 'Silver Linings Playbook,' David O. Russell is the master at getting his actors to give him something that he doesn't expect. He loves to keep things spontaneous. He talks to the actors throughout a take because, in real life, you don't know what the next person is going to say; you don't know when you're going to get interrupted.”
