That John Cassavetes Smirk
As a child, John Cassavetes chipped his front teeth in a fight. As his parents were too poor to buy him caps, Cassavetes didn’t smile for years. The experience made him aware of how others coped with misfortune. Later, when he started making films, his camera fixed on the facial tics and movements of his actors. (x)
I didn’t smile at all for a long time. I had an accident and some of my front teeth chipped. When I finally got enough money to have them fixed as an adult, I had gotten out of the habit of smiling.
