Don't Tread On The Full 'War Horse' Trailer

Jeez. Dude really loves that horse. Though we aren't shown any imagery of horses firing weapons at one another, the full-length War Horse trailer looks pretty good. The Steven Spielberg film tells the story of Joey, a horse purchased for World War I combat, and his owner as he joins the war in an effort to reclaim his horse. What the hell? I don't understand. Did the animal eat something that was important to him? Why is he so attached to that thing? Somebody's got to teach that kid how commerce works. We can find out for sure when the film is released on Christmas Day.
