Excellent article. Two quotes I'd add: First, one that I love from David Lean, who said in an interview with Barry Norman (at about seven minutes in):

"Reality on the screen... is a sort of bore. I don't mean that that the audience should sit there and think "That's unreal". But movies are a kind of dream, aren't they? And I think they should have an unreal edge to them."

Also, another from Stanley Kubrick (who said this in another Barry Norman interview, this time in the Radio Times):

"Ideas are a trap. You can't make a film based on an idea. You must have a story."
