First, the film took its sources from Raymond Thorp and Richard Bunker's book Crow Killer: The Saga of Liver-Eating Johnson (1958) along with Vardis Fisher's Mountain Man (1965). Both novels are still in print today.
Johnson was a legend, indeed, since few original sources mention him. There were multiple men named Johnson who lived in the west in that era, but he was distinguished by his nickname. Supposedly, the mountain man was born in New Jersey with the surname Garrison and served on a naval ship in the Mexican-American War. He deserted after striking an officer.
That's when he changed his name to John Johnson and headed to Alder Gulch, Montana Territory, to dig for gold. He may have cut wood and stacked them into cords for steamboats. He stood six foot or six foot two, around 260 pounds without a bit of body fat from all the hard work he did as a sailor, gold miner, wood-hawk, hunter, trapper, scout, soldier, whiskey-peddler, log cabin builder, deputy, guide, constable -- whatever he could do to earn money.
But the real legend of becoming "Liver Eating Johnson" and "Dapiek Absaroka" or Crow Killer began around 1847. Johnson had taken an Indian wife from the Flathead tribe, who was murdered by a band of Crow Indians. Johnson didn't take kindly to that, and hunted them down - cutting out and eating their livers after death. Crow Indians believed the liver was a vital organ on their path to the afterlife, so that was a true insult. The film, however, never mentions that in dialogue.
Several tales of Liver Eating Johnson - that of being attacked by a band of Blackfeet who planned to sell him to the Crow, escaping and surviving by eating the legs of a captor, may be attributed to another and far more notorious mountain man of that era, killer and cannibal Boone Helm. Other famous mountain men include Kit Carson, Jim Bridger, Old Bill Williams, James Clyman, John Colter, David Edward Jackson, Jedediah S. Smith, Doc Newell and Jonathan Warner.
Despite his former desertion under a different name, Johnson enlisted in the Union Army in 1864, Company H, 2nd Colorado Cavalry, and received an honorable discharge in 1865. He returned to Montana, preferring solitude, but did serve as deputy sheriff in Coulson and as town marshal in Red Lodge in the 1880s. By the end of his life, however, he spent his last month in a veterans home in Santa Monica, California. Johnson's body was relocated to Cody, Wyoming, from a Los Angeles cemetery after a 5th grade class and the teacher campaigned for it. The bronze statue below stands above Liver Eating Johnson's grave at Old Trail Town.
