In late August, 2019 RMK Films CEO Ron King travelled to England to do research and scout potential locations for the Millionaires’ Unit Limited Series. He visited several locations in London where the real events of 1917 took place. He also visited the military town of Aldershot where the British conducted trench warfare and flight training during World War I. He then visited two active aerodromes, one at Shuttleworth and the other at Stow Maries in Essex which operate flights of both authentic and replica WWI aircraft. The latter two locations are potential air fields where critical sequences could be filmed using full sized WWI aircraft.
