The Kingsman franchise will return later this year not with Kingsman 3 but a prequel that takes place a hundred years ago and aims to tell the story of the founding of the upper class secret service.

Aaron Taylor-Johnson, Gemma Arterton, Tom Hollander, and more have joined the cast of Kingsman: The Great Game, Matthew Vaughn's prequel Kingsman movie.

Vaughn has big plans for the Kingsman franchise, and the next step will be a World War I-set story that follows a new lead character by the name of Conrad, a young son of a British Duke, played by Harris Dickinson.

The plan is for Vaughn to direct both Kingsman: The Great Game and Kingsman 3 back-to-back, with just a short break in between. If that is still the plan, then the full cast and start of production on Kingsman: The Great Game signals the beginning of Vaughn's master plan to potentially close out the Kingsman story.
