Rex the Wonder Horse gets some screen competition in the form of Jack Perrin's magnificent white steed Starlight in Guardians of the West. Most of the film's heroics are handled by Perrin, who rescues heroine Ethyline Clair from the mortgage-holding villains. He also saves the girl from a raging forest fire (which looks like the real thing). On several occasions, however, it is Rex who precipitates Perrin's derring-do by tipping off the human hero about the perils facing the helpless Clair. Legend has it that Rex was one of the meanest horses ever to draw breath, but no one could deny that he was a magnificent screen presence.
