If the talks pan out, John will join a cast that consists of lead actor Taron Egerton and new additions Julianne Moore, Halle Berry and "Game of Thrones'" Pedro Pascal. The first poster for the "Kingsman" sequel also teases that Colin Firth's character, Harry Hart, may return from the grave for the next installment.
The first "Kingsman" film was based on the Mark Millar and Dave Gibbons comic book series "The Secret Service." The comic does not have a sequel, making the film more of an open canvas. The "Kingsman" film defied box office expectations and made $414.4 million worldwide, from a $81 million production budget.
