Spirit: Stallion of the Cimarron is a 2002 American animated western drama film that that was produced by DreamWorks Animation and released by DreamWorks Pictures. It follows the adventures of a young Kiger Mustang stallion living in the 19th century wild west. The film, written by John Fusco and directed by Kelly Asbury and Lorna Cook, was nominated for the Academy Award for Best Animated Feature. In contrast to the way animals are portrayed in an anthropomorphic style in other animated features, Spirit and his fellow horses communicate with each other through sounds and body language. Spirit's thoughts are narrated by his voice actor Matt Damon, but otherwise he has no dialogue. Wikipedia
Spirit: I couldn't understand it. She treated this scrawny two-legged like one of our kind, prancing around him like a love-struck yearling. It was down right unnatural.
