 The films horse trainer told Elliot Silverstein (qv) that the  scene where a horse leans against a wall with its front legs crossed  could not be shot because horses dont cross their legs, then that  it might be possible if he had a couple of days. Silverstein invoked  his rank as director and gave him an hour. The trainer plied the  horse with sugar cubes while repeatedly pushing its leg into  position, and they were able to get the shot.
