According to website 'Allmusic', "the producers and directors of the film wanted to use Gustav Holst's The Planets, but could not get permission".
Some movie posters for the film featured a fallen Statue of Liberty which was a design concept which has also been used for not just this film but for others. The titles are The Planet of the Apes (1968), Escape from New York (1981), The Jupiter Menace (1982), and The Day After Tomorrow (2004).
This documentary film's opening title card states: "The Great American Desert About 5000 B.C."
