While speaking with IGN, Mark Millar revealed a bit about the sequel to this year's "Kingsman: The Secret Service," a film based on a comic book series he created alongside artist Dave Gibbons. He specifically addressed "Kingsman" co-lead Colin Firth's role in the sequel, which was greenlit back in April after the first film became a surprise worldwide box office hit, earning over $410 million worldwide. For those that haven't seen it yet, however, we must put a spoiler warning right here before moving forward.

Those that saw "Kingsman" know that Colin Firth's character, the superspy Harry Hart, died right at the end of act two -- so how, exactly, can the actor have a part in the sequel?

"That's the conversation everyone's having right now, because part of what made that movie work is Colin," said Millar. "Colin's fantastic, it was a two-hander, that film. You also want to have the integrity of the story, so if you are bringing him back, it has to make sense. That's where it is at at the moment. Beats of the story have been done. [Screenplay co-writers] Matthew [Vaughn] and Jane [Goldman] are working on it at the moment. Some things have to be worked out, some decisions have still to be made and everything, so it's all fairly amorphous, but all going well."

Millar discussed the details of the character's possible resurrection, revealing that he has the utmost faith in director Vaughn. "It's funny because there's a lot of conversations like that, like should he have an evil brother, Colin with a mustache? Or is he a ghost or whatever? The guys have a plan. I can't spoil it just now because the final decision is still to be made. It'll be good. Vaughan's funny. He's done Layer Cake, Stardust, Kick-Ass, X-Men: First Class, and Kingsman. Even Spielberg had made 1941 by his third movie, so I trust him. He's done five good movies." You can watch the interview below.
