DreamWorks SKG purchased a horse as the model for Spirit and brought the horse to the animation studio in Glendale, California for the animators to study . In the sound department, recordings of real horses were used for the sounds of the many horse characters' hoof beats as well as their vocalizations . None of the animal characters in the film speak English beyond occasional reflective narration from the protagonist mustang (voice of Matt Damon). Many of the animators who worked on Spirit also worked on Shrek 2, and their influence can be seen in the horses in that film, such as Prince Charming's horse from the opening sequence and Donkey's horse form . Makers of the film took a trip to the western United States to view scenic places that they could use as inspiration for locations in the film . The homeland of the mustangs and Lakotas is based on Glacier National Park, Yellowstone National Park, Yosemite National Park, and the Grand Teton mountain range . The cavalry outpost appears to be located at Monument Valley . The canyon of the climax looks like Bryce Canyon and the Grand Canyon . </P>
