Most difficult thing in the world, to write a play. Do you know the story of Shaw at the Fabian society? H.G. Welles said "I'm terribly sorry I've missed the last five meetings, I've been terribly busy, I'm engaged in writing a scientific pamphlet on the effects of radioactivity in 1984 and I've produced a novel, and various pieces of science fiction to do, and I've had a bit of personal trouble, and I had my copy to bring out for the newspaper." Shaw leapt up and said, "I've not missed one meeting, and I have written a play!" hardest thing in the world. If it were easy they'd all be at it.
You talk about auteur de cinema having things in their heads and putting them all across, can you imagine Shakespeare writing screenplays?
If I'm not at my study by 10:00, 10:30, forget it, I can't write a word.
Writing is a kind of performing art, and I can't sit down to write unless I'm dressed. I don't mean dressed in a suit, but dressed well and comfortably and I have to be shaved and bathed.
