Man is the only species who has created destructive weapons to destroy himself. No other species is capable of that. In all my war movies, I wanted to show the intense kind of hate that man reveals during war. It is the darkest and most insane time, and yet we attach so many values to war. Honor, country, heroism.
Death is the most important emotion.
But war has not been accurately depicted in the movies. The screen has hardly ever shown how a man is really killed. It isn't pretty. It's too grim for an audience to see. Producers won't allow you to show these things.
