Those poor cattle.

There is an horrendous scene in this film where a herd of cattle is being driven down the main street of the town and, as they pass the general store, the store explodes in a huge ball of flame. The cattle leap up into the air in shock and one of them can be seen engulfed in flames across its back and is leaping up into the air. It must have been in agony. It all looks real because it is real. Real cattle, real explosion. I doubt very much if a film company would be allowed to inflict such suffering on live animals these days.
