One year after his success in The Graduate, Dustin Hoffman couldn’t get a job playing a dead guy in a cowboy movie. No one believed he could act. So he put on a raincoat and took a chance at night in Central Park. This scene from his next movie, Midnight Cowboy, is one of the most iconic scenes of the 20th century. And it wasn’t in the script. That was a real moment, a real taxi, a real reaction.
