I find playwriting to be incredibly difficult compared to screenwriting. Part of it is that I grew up watching movies and not watching plays.
I think it is the weak and the young and the minorities that you need to look after to get a healthy creative environment - to get a lot of choices, a lot of different styles of music, a lot experimental stuff that everyone else feeds off.
I run six-to-eight miles a day, plus weights and aerobics in the lunch hour. I also lie a lot, which keeps me thin.
