Remember the Robert Redford movie, "Horse Whisperer"? The protagonist in that film is patterned after Buck Brannaman, the real-life wrangler who ended up coaching Redford in the role. "Buck," the documentary about Buck and his work, is much more than a profile  It reveals a lot about human nature and the choice to overcome an excruciating past. Look for this little flick to to pull off an Oscar nomination. It already won the "Audience" award at the 2011 Sundance Film Festival.
