A friend of mine from college made this movie with his brother. It follows 6 horses and their human entourages as they try to make it to the Kentucky Derby. Amazingly, one of the horses was Barbaro. It's a great sports story, even if you don't follow racing or loiter at the OTB.
It's getting some great reviews and I highly recommend it.
In NYC it's playing at cinema village (12th St/University)
