One movie I come back to time and again is 'The Hustler.' I don't think there's better dialogue in any film.
“We take people to the threshold of religion. Our aim is to induce immediate experience that is beyond the odd, beyond the strange, and beyond the weird. It verges on the wholly other.”
“What you lose in blindness is the space around you, the place where you are, and without that you might not exist. You could be nowhere at all.”
