Although the remnants of the escaped Spanish horse are protected by the 1971 Free-Roaming Wild Horse and Burro Act, each year thousands are removed from public lands across the American West to reduce competition between horses and domestic livestock.

El Caballo documents one of the most complex wildlife management issues today. Where do modern wild horses fit in our view of the natural world?

Note: This version is shortened from the director's original 54-minute cut and was edited with educational and group screenings in mind, where length is an important factor. The director describes the difference between the two versions as follows:

"The 54-minute version of EL CABALLO includes a more significant discussion about the origins and evolution of horses in North America. It also includes a more in-depth history beginning with the 're-introduction' of Equus cabalus to North America, acquisition and use by Native Americans, and eventual capture and sale by wild horse 'mustangers.' Current management of wild horse populations on public lands is covered fairly well in both versions, but the longer version contains a somewhat more complete picture of BLM management."
