Kingsman director Matthew Vaughn has explained why the prequel movie The King’s Man was made before the long-awaited Kingsman 3. Serving as the prequel to both 2014’s Kingsman: The Secret Service and 2017’s Kingsman: The Golden Circle, 2021’s The King’s Man charted the formation of the Kingsman private secret intelligence organization during the events of World War I. Initially planned to be released in 2019, the movie was pushed back several times owing to both Disney’s acquisition of 20th Century Fox and the later impacts of the COVID-19 pandemic.
