Ersatz though this movie gun's sideplates may be, the Winchester 1887 itself has a long and proud history as America's first successful repeating shotgun. Designed by the legendary John Browning, the gun was created for use with blackpowder-powered shells; the newer smokeless-powder rounds were too much for the 1887. Although Browning originally proposed that a pump action would make for a sturdier, more reliable repeating shotgun, Winchester demurred—at the time, they were known as a lever-action rifle company, and preferred that any shotgun they produced follow the same strategy. (By 1893, however, Winchester did move forward with a pump-action shotgun of Browning's design.)
In Ghost Rider, Cage's character Johnny Blaze sells his soul to the devil in exchange for his father's health...but the devil finds a way to cheat Blaze. Eventually, he's persuaded into accepting the role of the "Ghost Rider," a spirit charged with capturing errant evil souls and returning them to Perdition. The Rider doesn't really need a shotgun, but since Blaze is perfectly human during daylight hours, he frequently finds need for it. Unfortunately, as sometimes happens in Hollywood, the movie makes a mistake with the firearm: Johnny and his girlfriend fire it a total of seven times without reloading—and the gun only holds five rounds in its tubular magazine.
