London is completely unpredictable when it comes to weather. You'll start a scene and it's a beautiful morning. You get there at 6 in the morning set up you start the scene start shooting. Three hours later it is pitch black and rainy.
But I work harder now because I have so much more exposure. And actually the harder you work as a writer the better you get at it. It's like anything else. It's a muscle you have to exercise. I write more now than ever.
