Cassavetes sums it up for me.
"I like to act in films, I like to shoot ‘em, I like to direct ‘em, I like to be around ‘em. I like the feel of it and it’s something I respect. It doesn’t make any difference whether it’s a crappy film or a good film. Anyone who can make a film, I already love. But I feel sorry if they don’t put any thought in it because then they missed the boat." -John Cassavetes
