It's like you asked me about the depression thing: you grope towards an understanding of whatever it is your going through, and it's not personal, there are forces in play around you, and you seek to understand them and that way you can go on.
To me, the difference between New York and London is that things are boring and staid in London.
But I notice that there is a lack of darkness in my movies and I don't know where that comes from.
