The Agony and the Ecstasy (1965)
Raphael: For what is an artist in this world but a servant, a lackey for the rich and powerful? Before we even begin to work, to feed this craving of ours, we must find a patron, a rich man of affairs, or a merchant, or a prince or... a Pope. We must bow, fawn, kiss hands to be able to do the things we must do or die.
Raphael: We are harlots always peddling beauty at the doorsteps of the mighty.
Michelangelo: If it comes to that, I won't be an artist.
Raphael: [scoffs] You'll always be an artist. You have no choice.
