In case you are as pumped as I am and want to learn more about not just the movie, but the Broadway play that is already out, here is the link to the website:
War Horse on Broadway at Lincoln Center Theater's Vivian Beaumont Theater
I would HIGHLY suggest checking all the videos out. If you think the handspring puppets are as cool as I do, and you have 20 minutes of free time, then you should watch this video on TED about how the creators of the handspring puppets created them. VERY VERY interesting!
