Q&A with David Hare
A: It's more about (director) Stephen Daldry. He's a thorough director and shot more than they eventually used. When you embark on a film with him, you can kiss goodbye to two years of your life! He will look at the events from every possible angle and constantly be asking if we're missing out on something. So we were filming for a long time, but we had to edit quickly. When you're writing about three different periods, especially during the time when Michael is writing to Hanna, which covers an immense ground, you have make decisions like that.
