Writing is such lonely work that I try to keep myself cheered up. If something strikes me as funny in the act of writing, I throw it in just to amuse myself. If I think it's funny I assume a few other people will find it funny, and that seems to me to be a good day's work.
I stopped directing in 2001 for four or five years, until I did the TV series 'Masters Of Horror. ' I had been working steadily as a director since 1970. That's a long time. I was burned out.
