Here's the first teaser for Steven Spielberg's "War Horse," an adaptation of the 1982 Michael Morpurgo children's book that more-recently inspired a stage play. The story: A horse "drafted" into the Cavalry during World War I suffers mightily as he tries to survive the war and ultimately get back to it's owner, a young English boy - who is also searching for him. Wow. Might as well have titled it, "Please make a movie out of me, Steven Spielberg."
As I see it, there's only two ways this can concievably go: Either it's "Amistad" again (i.e. well-meaning, well-made but ultimately uninvolving stuff) OR we're about to add another title to the "movies it's okay for men to cry at" list.
