Trigger (originally named Golden Cloud, 1932--3 July 1965) was a 15.3 hands (63 inches, 160 cm) palomino horse, made famous in American Western films with his owner/rider, cowboy star Roy Rogers. Film career: Golden Cloud made his movie debut as the mount of Maid Marian, played by Olivia de Havilland in The Adventures of Robin Hood (1938). A short while later, when Roy was preparing to make his first movie in a starring role, he was offered a choice of five rented "movie" horses to ride and chose Golden Cloud. Roy bought him that same year, 1938, and renamed him Trigger for his quickness, not only of foot but of mind. Trigger was ridden by Rogers in many of his motion pictures, becoming much loved by the youthful audience that saw him on film and in Rogers' 1950s television series with his wife Dale Evans ... Trigger became the most famous horse in film entertainment, even having his own Dell comic book recounting his exploits.)
