Matthew Vaughn's Kingsman prequel, The Great Game, has added more names to its expanding cast. Reuniting with his Kick-Ass star, Vaughn has drafted in Aaron Taylor-Johnson for an undisclosed role in his period set spy thriller.

The new cast members don't end there, Djimon Hounsou (Captain Marvel), Alison Steadman (Orphan Black), and Tom Hollander (Rev, Bird Box) have also signed up for the prequel. There a currently no details on Steadman and Hounsou's characters, but Hollander is credited on IMDB as playing three different roles which include King George V, The Kaiser; and a Russian Tsar.

The next entry in the Kingsman franchise takes us back to the formation of the dapper spy organization in the early 1900s. Harris Dickinson (Trust) will star as Conrad, a spirited young man who is desperate to do his bit and fight in World War I. Unable to enlist; he finds himself mentored by Ralph Fiennes' character for a dangerous mission of the utmost importance. The new cast additions join the already confirmed Charlies Dance (Game of Thrones), Daniel Brühl (Captain America: Civil War) and  Rhys Ifans (The Amazing Spider-Man).

Matthew Vaughn is staying in the Kingsman business for the foreseeable future as he's expected to go into pre-production on the sequel to The Golden Circle shortly after he's finished on The Great Game. That's not all; the US set spin-off that will expand the world of their American counterparts (Statesman) is also in development with Channing Tatum set to reprise his role from The Golden Circle.

Filming on The Great Game is currently underway in the UK for a November launch in cinemas. Meeting that release date seems a tad ambitious, so we'll have to wait and see if that's still the case in a couple of months time.
