In the film brothers Frank, Sim, and John are lynched. In reality John was not hanged by the vigilantes but had been imprisoned and lived until 1895. Bill was the third brother hanged although in the film he is killed in a bungled bank robbery early in the film.
Set in Indiana in 1866, the opening sequences reveal telephone poles and telephone lines in the background. Also, the U.S. and California State flag are shown on a flagpole in the background. (The film was shot in California)
Although the film is set in the Midwestern state of Indiana, the opening sequence shows a desert landscape and the kind of towering buttes found in the Southwest--e.g., Utah and Arizona--and not on the flat prairies of Indiana.
