This was the last serial produced by The Wharton Brothers. The war in Europe had ended and the influenza epidemic was sweeping the country. Attendance at movie houses was declining and nobody was interested in war-themed films. So this film, based on a real German espionage case, was a major financial disaster that effectively put the Whartons out of business.
