Turning one's novel into a movie script is rather like making a series of sketches for a painting that has long ago been finished and framed.
I do not begin my novel at the beginning, I do not reach chapter three before I reach chapter four, I do not go dutifully from one page to the next, in consecutive order; no, I pick out a bit here and a bit there, till I have filled all the gaps on paper. This is why I like writing my stories and novels on index cards, numbering them later when the whole set is complete. Every card is rewritten many times.
