Director Matthew Vaughn has teased several details regarding the recently confirmed action sequel, Kingsman 3, revealing that both Eggsy and Harry will be back for one last ride. Not only will the highly anticipated threequel feature the popular duo’s return, Vaughn divulged a few more details in a conversation with Collider, including that several more familiar faces could also make a comeback, and that the movie will center on a will-they-won't-they dynamic between Eggsy and Harry.

“Eggsy and Harry [will be in it], obviously. But it’s the gang coming back together and it’s one of those moments that…when we wrote the screenplay, it was very much about, okay, I saw how people loved the relationship of Eggsy and Harry. So we just came up with this thing, what could be the ultimate reason for them to either fall in love or to hate each other forever? So that’s what this movie is all about is will they or won’t they, let’s just say.”

The relationship between Taron Egerton’s Gary "Eggsy" Unwin's and Colin Firth’s Harry Hart AKA Galahad has been an endearing one ever since their first meeting back in 2014’s Kingsman: The Secret Service. Sitting somewhere between a mentor-mentee, father/son, best friends forever bond, putting the spotlight on Eggsy and Harry for Kingsman 3 certainly makes the most sense, with Matthew Vaughn hoping to bring their journey to a satisfying conclusion. Though, from the sounds of it, they will have to navigate some serious drama first.

Introduced in Kingsman: The Secret Service, which saw Eggsy recruited into the secret spy organization, and saving the world after Harry’s apparent death, a 2017 sequel, Kingsman: The Golden Circle, saw Harry resurrected while the Kingsman organization was wiped out. Thus, Kingsman 3 is likely to see the pair attempt to build the secret spy group from the ground up. A task that will no doubt bring their differences to the forefront.

Someone else who hopes to return to the Kingsman fray is actor Mark Strong, whose character Merlin was seemingly killed during the finale of The Golden Circle. "I don't know. I'd love to because I love making those movies,” Strong said back in May. “I thought that triumvirate, that connection of me, Colin (Firth), and Taron (Egerton) was a great little gang. I was quite sad, I think, as were a lot of people, when he comes to his dynamic end, shall we say? At the end of the second one. I think there is a third one, and that universe, anything can happen as you well know. I mean, Colin got shot in the eye and comes back and he's fine. It's fantasy, so I'm not ruling it out."

Before all that, Matthew Vaughn returns to the franchise with this month’s The King’s Man. Working from a screenplay by Vaughn and Karl Gajdusek and with a story by Vaughn, The King's Man stars Ralph Fiennes, Gemma Arterton, Rhys Ifans, Matthew Goode, Tom Hollander, Harris Dickinson, Daniel Brühl, Djimon Hounsou, and Charles Dance and finds a collection of history's worst tyrants and criminal masterminds gather together to plot a war to wipe out millions of people and destroy humanity. One man and his protégé must race against time to stop them, as the movie reveals the origin of the elite secret service.

The King's Man is scheduled to be released on Dec. 22, 2021, having been delayed several times due to the ongoing global situation.
