Too Quotes (page 24)
Every 20 minutes you've got to have a bump, you've got to have a change in course, you've got to unsettle the audience. It can't be too predictable so something has to happen. I think that was something that Hitchcock did very well too. You couldn't let an audience feel too settled in.
Barbara Broccoli
Life is insanely robust, though we can make species go extinct, and this is the bad thing. So I always make the point that you can't say, 'Is it too late?' That is the terrible question, because either answer promotes inaction. If it's too late, you don't need to act; if it's not too late, you don't need to act.
Kim Stanley Robinson
