Film is a dramatised reality and it is the director's job to make it appear real... an audience should not be conscious of technique.
So it is fair enough that you are paying me what I ask for, because it is my name you are using to sell the film. If the producer gives me a guarantee that he will sell the film at a lower price to the distributors, fair enough, then I will charge less!
I want to do movies that I'm proud of where my kids, at some point, can see and I can feel comfortable sitting there watching it with them. And just that move people. That make people feel a little bit better about themselves when they leave the theatre.
