From the Neil Gaiman: Dream Dangerously :) (you can watch it here in US or with US vpn :) <3)
Terry Pratchett: One day he rang me up and said, "I've started a book and, I think it's good, but I haven't the faintest idea where it goes." So, I said, "All right, well, send me the pages." And I read it and wrote him back and said, "I don't know where it goes either, but I do know what happens next."
Neil Gaiman: I was pretty much nocturnal then, so I would write my chunk of Good Omens before I went to bed, and I'd go to sleep about five o'clock in the morning and I'd get up about one o'clock in the afternoon and my answering machine would be flashing on, and I'd press the button and a voice would say, "Get up, get up you lazy bastard, I've just written a good bit."
Terry Pratchett: We did it as a kind of holiday, because if it crashed and burned, nobody would notice.
