You make a compelling argument, but I'm afraid I'm going to have to bring in the wolves if you're going to open the whole barn up to discussion.
They did kill the horse that fell down the steps in Andrei Rublev, too, so animals were certainly harmed during the production.
I don't know why you mentioned that the cow wasn't hurt, though. I just want to know how the old lady who got a spear in the chest is doing.
