As portrayed on the screen, white-haired Bill "Hopalong" Cassidy was usually clad strikingly in black (including his hat, an exception to the Western film stereotype that only villains wore black hats). He was reserved and well spoken, with a sense of fair play. He was often called upon to intercede when dishonest characters took advantage of honest citizens. "Hoppy" and his white horse, Topper, usually traveled through the West with two companions—one young and trouble-prone with a weakness for damsels in distress, the other older, comically awkward and outspoken.
