In an interview with Yahoo! Movies, "Kingsman" director Matthew Vaughn -- who brought Mark Millar and Dave Gibbons' Icon Comics series "The Secret Service" to the big screen -- revealed he is working on a sequel film.

"Well, the good news is that I'm writing it next door at the moment. If I think I can get the script good enough, then we are making it," Vaughn revealed when asked about a potential sequel. Fox greenlit the sequel earlier this year.

Vaughn also disclosed that we may see an American Kingsman in the forthcoming sequel and why he felt drawn so often to Millar's work.

The first film starred Colin Firth and earned over $400 million the global box office. "Kingsman: The Secret Service" follows Eggsy (Taron Egerton), a poor Londoner who gets the chance of a lifetime when Harry Hart (Firth) offers him the chance to join the Kingsman, a British secret service unit usually reserved for the well bred and elite. Eggsy and Roxy (Sophie Cookson), another Kingsman recruit, must go up against an evil CEO named Valentine (Samuel L. Jackson) and his blade-legged and dangerous assistant called Gazelle (Sofia Boutella).

Released on February 13, "Kingsman: The Secret Service" was directed and produced by Matthew Vaughn, who co-wrote the script with Jane Goldman, and also starred Michael Caine and Mark Strong.
