"A Lesser Sort of War" was initially submitted to the Atlantic Filmmakers Cooperative Film 5 Program in 2005 but was not selected.
Director Michael Ray Fox photographed as many of the scenes as possible in the actual locations where they historically took place, save for buildings that are no longer standing.
Hal Thompson's script was based on the true story of Joseph Howe's pistol duel with John Halliburton.
Charles T. Conrad was originally considered for the role of John Halliburton.
While shooting at Citadel Hill, Tom Selleck arrived at the set of 'A Lesser Sort of War' for a private guided tour. Because the film's production interfered with Tom Selleck's tour, special accommodations were made for his inconvenience. Producer Michael Ray Fox listed Tom Selleck's name in the "Special Thanks" list upon the initial release but later removed it in future release at the request of our broadcaster.
