"The written word is the basic of everything. Most important, the idea, and after that, the dialogue. You can rehash the dialogue as you go along, it 's disgraceful to have to do this, but now and again you have no choice."

In real life, people fumble their words. They repeat themselves and stare blankly off into space and don't listen properly to what other people are saying. I find that kind of speech fascinating but screenwriters never write dialogue like that because it doesn't look good on the page.
