Roy Rogers' golden palomino, Trigger, was the perhaps the most famous horse in film—more popular than the man himself among certain fans. In its expanded second edition, this detailed look at the animals and men who created the legend of "the smartest horse in the movies" examines the life story of the original Trigger—and his doubles, particularly Little Trigger, the extraordinary trick horse. Movies in which Trigger appeared without Rogers are discussed. More than 200 photographs (90 new to this edition) and 30,000 words of additional material are included, covering unresolved aspects of Trigger's story, controversies surrounding the sale of the Roy Roger's Museum collection and the fate of his legacy.
