The most memorable thing to me about the movie was the musical score. Most of its viewers were probably unaware it was built around the tune to an old hymn, “How Firm a Foundation.” The fourth verse of the hymn says:
When through fiery trials your pathway shall lie
My grace, all sufficient, shall be your supply.
The fire shall not harm you. I only design
Your dross to consume and your gold to refine.
The version used for the film was part of a larger work by Virgil Thompson titled "The Plough the Broke the Plains"--the irony of plowshares into swords shattering the peaceful plains of Nebraska.
