"In COWBOY there was a moment that was pure. I was crossing the street with Jon Voight; we were being filmed by a hidden camera, and in costume we weren't recognizable. And a taxicab almost hit us. I got very angry, because I got scared--but I didn't break out of character. I got angry as Ratso, and I started hitting the cab on the hood, yelling, "I'm walkin' here!" It was the very essence of what I wanted to convey about Ratso--his dignity. We may see him as a low-life, but he asserts himself. And I think people recognized the truth of it."
Playboy, April 1975
