I haven't done it by myself at all. I've been surrounded by a really, really good crew of all ages. I think it's important to have a good age range in the crew so that some of us have experienced that period, or something close to that. But the script, of course, is really inspiring and you just have to trust that. Sometimes on film a glass can be as big as a car, so if the details are right, then they take up as much space on screen as the streets that we didn't have a chance to show as London really has changed since then.

We just worked hard to not just get things right and authentic, but also to make it consistent and visually right. For instance, there are colours that aren't in the film that would have been there in reality. I think part of the look of the film not only has to do with the way it's shot and lit, but also the lack of certain colours that give it a softness which really suits it because there's more focus on the characters. For instance, there's no yellow at all until we get to Miss Stubbs' flat at the very end.

I loved the tone and the characters. They're all very different and they're all very typical for their time. When you read the screenplay you feel like meeting them and getting them off the page and on to the screen.

I've talked a lot about the discipline and high, high skills of the British actors as seen from my Danish point of view. But I also have to say that Peter is unusually intelligent, humble and a good friend to everyone.
