Query: Buck

Remember that Robert Redford movie The Horse Whisperer? Yep, that was loosely based on a real guy, and the remarkable documentary Buck tells his story. Unsurprisingly, it turns out that Buck Brannaman's life never followed a script -- director Cindy Meehl demonstrates that Buck's remarkable patience and wisdom was incredibly hard fought. The man who trains horses like nobody else was the victim of child abuse for many years, but Buck endured, and testimonials to his gentle teaching methods -- including high praise from Redford himself -- help to make Buck, an inspiring documentary.
