Following the success of the Matthew Vaughn-directed movie ‘Kingsman: The Secret Service’, 20th Century Fox is reportedly developing a sequel to the spy action comedy film.

There have been no official announcements about the making of a second movie, and Vaughn is not expected to take the director’s chair once more as he has been set to join the team of the ‘Flash Gordon’ reboot.

Vaughn, who previously worked on ‘X-Men: First Class’ and ‘Kick-Ass’, is recognized as a co-writer in the original comic book series with which a second volume will reportedly be published.

Drawing out from the Icon Comics miniseries in 2012 by Dave Gibbons and Mark Millar, ‘Kingsman: The Secret Service’ follows the story of a secret spy agency which recruits a capable street kid and lets him join the organization’s competitive training program at the same time that a global threat relating to mass genocide arises from an evil tech genius.

Academy Award-winning actors Colin Firth and Michael Caine star in the movie alongside Academy Award nominee Samuel L. Jackson. ‘The Imitation Game’ actor Mark Strong also appears in the film as well as newcomers Taron Egerton, Sofia Boutella and Sophie Cookson.

Penned by Vaughn and Jane Goldman, ‘Kingsman: The Secret Service’ has pulled in more than $401 million at the international box office. The movie has been set for a Digital HD debut on May 15 as well as a release for Blu-ray and DVD on June 9.

Although Vaughn has not confirmed that a sequel is actually in the works, he previously mentioned that he is willing to create a second installment that would highlight the story of Eggsy, played by Egerton, as he has certainly raised questions about becoming a refined spy despite his rebellious past.

However, despite a potential story that will follow the former street punk character, Vaughn also mentioned that this would not ensure the comeback of Firth in the follow-up movie.

“A lot of people are very upset that Colin might not be in the sequel but I'm coming up with ideas at the moment," Vaughn explained last February. "If people buy tickets in America, I've got a feeling we'll figure out a way for having Colin back."
