Pie was quite the horse for Jimmy Stewart. I heard of this story and just found proof.
http://www.npr.org/2016/03/21/47128...e-horses-that-captured-moviegoers-hearts"they just became so attuned to each other that in one film, "The Far Country," Stewart had developed such a rapport with him that he was able to get the horse to do something at liberty all by himself when the trainer was not around. They were on this location. The trainer wasn't on the set. And the horse needed to walk from one end of a street to another with no ropes on him or anything, and Stewart just went up to him, he said he whispered in his ear and told him what he needed him to do. And the horse did it. And everyone on the set was absolutely amazed, and Stewart just said, that was Pie. That's what he did. So he absolutely had an incredible bond with the horse"
