I remember this one story a production man told about him. The man said he and a couple others were gathered around during a filming break (on the set of Giant) and they were playing a lasso game. Whoever had the rope had to latch it on to some object or somethign like that. Anyway, one of the men couldn't do it and so all the other guys were laughing at him and giving him a hard time. Later, "Jimmy" as he called him, took him to his trailer and taught him how to do it. The directors and producers were calling Dean back to the set but he wouldn't leave until the man learned how to do it. Finally, the guy got it and managed to lasso the rope correctly. I remember he said it really touched his heart how sweet James was to him.
