In 1960, production house Drummer Films previously produced a film with the same 'Fourteen Hundred Zulu' title. It showed ''an amphibious exercise with the Royal Navy and Royal Marines'' according to the Imperial War Museum.
The film's closing title card epilogue reads: ''It is upon the Navy upon the good providence of God that the Wealth, Safety and Strength of the Kingdom do chiefly depend. Articles of War 1661''.
The film's 'Fourteen Hundred Zulu' title is a ''naval reference for 2pm Greenwich Mean Time'' according to the Imperial War Museum.
