PIERRE, S.D. (AP) — A letter from the man whose story is told in the movie "The Revenant" is on display at the Cultural Heritage Center in Pierre.

The one-page letter from frontiersman Hugh Glass was sent to the parents of another man who had been killed by American Indians in 1823. A family member of the slain man donated it to the South Dakota State Historical Society at the turn of the 20th century.

Officials speculate that since Glass was reportedly illiterate, he likely dictated the letter to an acquaintance.

Glass was attacked by a grizzly bear near Lemmon, South Dakota, in 1823. He crawled 200 miles to get revenge on his fur trapping companions who left him for dead.

Interest in the movie prompted the Historical Society to display the letter.
