The horse behind DreamWorks' 2002 film Spirit: Stallion of the Cimarron was a real Kiger mustang named Donner. Animators brought him to the studio and spent months watching how his muscles moved and his face changed with his mood. After the film, DreamWorks donated him to a wild horse sanctuary in California, where he was renamed Spirit. He turned 31 on May 8, 2026 - and fans still visit him.
