 One of Sam Elliott (qv)s conditions to do the part was to have  him carry a rifle in a scene instead of the scripted shotgun.  Jason Reitman (qv) agreed to change the script. When they were  about to do the scene, Reitman realized that he had forgotten about  the rifle and went to the prop wagon frantically hoping to find one.  There were three guns laying on the tailgate, two shotguns and a  rifle. When Elliott picked up the rifle, Reitman breathed a sigh of  relief. He asked Elliott if he needed instruction on how to use it.  Elliott declined and said that he knew how to use it because the  rifle was his.
