One of my favorite scenes
Ebert: "In On the Waterfront, there's a moment when Terry goes for a walk in the park with Edie (Eva Marie Saint), the sister of a man who has been thrown off a roof for talking to crime investigators. She drops a glove. He picks it up, and instead of handing it back, he pulls it on over his own workers' hands. A small piece of business on the edge of the shot, but it provides texture."
