The Flame and the Arrow (1950)
Dardo Bartoli: I learned a long time ago, my lady, never trust a mountain cat when she stops snarling and never trust a woman when your back is turned.
Skinner: ...we're civilized and the art of civilization is doing natural things in an unnatural way.
Marchese Alessandro de Granazia: If only I could be sure you're as honest as you are pretty, but then with a collar around your neck... it's hard to tell whether your throat's blushing from passion or deceit.
Dardo Bartoli: Now, Marchese, we're in the dark where a sword is just a long knife.
