Other mistake: At the beginning after Dunbar leaves the surgery area, he walks up to fence where a soldier is lying down. Next to him is an apple with the grocery sticker on it. (04:49:00)
Other mistake: Dunbar has to race back to the fort in the middle of having a shave. The amount of soap on his face alters shot to shot.
Revealing mistake: In the extended version of the film during the buffalo hunt, there is a shot of a buffalo making a turn and in the distant horizon, you can briefly see a modern radio tower on top of a hill.
John Dunbar: The strangeness of this life cannot be measured: in trying to produce my own death, I was elevated to the status of a living hero.
Trivia: The wolf in the film was played by two different wolves. Neither knew how to howl, so a third wolf had to be brought in for the howling scene.
Answer: He shaved it as he began spending more time with the Lakota. Native American tribes rarely accepted facial hair. As you can see, none of the other Lakota men have any. He also grew his hair longer as an abandonment of his military lifestyle.
