James Bernard was most famous for composing the scores to numerous Hammer horrors, including Horror of Dracula. Ironically, however, it was for this film that he won his only Oscar - as co-writer.
First original cinema score of John Addison
Presently available version, as broadcast on Turner Classic Movies, has been cropped to fit the 16:9 wide screen ratio, despite the fact that it was filmed in the traditional 4:3.
The film has a story very similar to The Peacemaker. In fact they have a number of plot points in the finale that are similar: 1. The final scene of disarming the bomb takes place in a church. 2. The person with the bomb carries it in a small bag: a backpack for The Peacemaker, valise for Seven Days to Noon. 3. The person carrying the bomb is shot at the end, before the bomb is defused. 4. A man and a woman are the people who confront the person with the bomb at the end. 5. Of the man and woman in both movies, one is a nuclear bomb expert: in Seven Days to Noon it's the man; in The Peacemaker, it's the woman.
There are a number of literary references in Seven Days to Noon: Among the jottings on Professor Willingdon's notes -- "The wicked beareth rule" is from the Bible, Proverbs 29:2 (...when the wicked beareth rule, the people mourn) and "Thus with a mighty fall shall Babylon the great city be cast down" Revelation 18:21; "Dark, dark, dark, amid the blaze of noon" comes from John Milton's Samson Agonistes, a play about the biblical character, Samson, who is granted the power to destroy the temple and kill all the Philistines (and himself). The professor later quotes Revelation 6:4, "The horse came forth, the red horse, and to him that sat thereon was given to take the peace from the earth. And there was given unto him a great sword." The speaker in Hyde Park says "There shall be wars and rumors of wars." Nearly identical words are found in Matthew 24:6, Mark 13:7 and the Book of Mormon, 2 Nephi 25:12. A man carries a sandwich board quoting "The wages of sin is death," again from the Bible, Romans 6:23.
