Continuity: When Jack Crabb is shown drunk during a heavy rainstorm shots alternate back and forth from being on an overcast day to being ones in bright sunshine.
Revealing mistakes: When Shadow That Comes In Sight rescues young Jack and Caroline after their parents were killed, you can see her put her foot up to a stirrup as she mounts the horse behind Shadow. When she dismounts it appears that Shadow, like most other Cheyennes, rides bareback.
Anachronisms: Following the movie time line, Jack Crabbe should have been rescued from the Indians around 1865. When he enters his gunfighter period around 1866, Jack is carrying two 1873 Colt Peacemakers while Hickock's pistol is an 1882 Colt.
Factual errors: Custer's attack on the Cheyenne at the Washita River occurred in the winter of 1868. Since Wild Bill Hickock was shot in the summer of 1876, Jack's drunk period would have lasted about eight years. Also the Battle of Little Big Horn was on June 25, 1876; Hickock was killed August 2, 1876, more than one month later.
Revealing mistakes: During the credits at the beginning of the movie, young Jack comes out of hiding and looks at a man's body, with an arrow sticking up out of it. The top of the arrow moves slowly as the "dead" man breathes.
Continuity: As Custer approaches the Little Big Horn he is mounted on a white horse. It subsequently changes to a brown horse.
Continuity: After Little Big Man is married to his first wife, Olga, and the two are moving out west, Indians attack the carriage they're riding in. After Little Big Man makes his way to the front of the carriage, where one of the drivers has been shot, the body of the dead driver appears and disappears between shots.
Anachronisms: When Jack first sees Mr. Merriweather, Merriweather is using a bass drum pedal. The first bass drum pedal was not patented until 1909 by William F. Ludwig.
