I was disappointed in the Seabiscuit movie. Too much emphasis on the people and the times and not enough on the horse. I read about Seabiscuit in a childrens' book years ago when I was a little kid. He quickly became my favorite horse. And then there was Northern Dancer. But Secretariat was the greatest. He had to be put down because of laminitis, too.
I liked the movie...part of it was filmed just a mile or two from were I work. A little local color. The book was wonderful. I read the same kids book too. SeaBiscuit is still far and away my favorite race horse.
