The Nebraskan

Fort Kearny, where the 1st Nebraska Cavalry troops are stationed in the movie, was an actual U.S. army post located on the south bank of the Platte River. It is inactive, but still stands and is a Nebraska state historical park. A half-mile to the east is Fort Kearny State Recreation Area, which contains a small lake and numerous camping sites.

A motor, likely a generator, is audible during the dialogue of several scenes and is particularly noticeable at six minutes into the film. Motors could not have been a natural background noise in Nebraska during the 1860's.
