Kingsman: The Golden Circle is still getting its cast together. And boy, what a cast this will be. Already announced are Julianne Moore, Halle Berry and original star Taron Egerton. Elton John is in talks to possibly play himself. And now, Channing Tatum has boarded the sequel. The actor made the announcement himself on his personal Twitter Account.

There is no word yet on which character Channing Tatum will take on. Though, it sounds like he is set to play a southerner with good manners. The movie is directed by original Kingsman: The Secret Service director Matthew Vaughn. The tweet came with the second in what appears to be a series of teaser posters. The tagline on this particular poster reads as such.

It was revealed just earlier this week that icon Sir Elton John is in talks for a role. No details were given for the character he may play, but it sounds like the musician may be playing himself. Regardless of his role, if a deal is finalized, Elton John joins a cast that already includes original Kingsman: The Secret Service stars Taron Egerton as Eggsy, Mark Strong as Merlin and Edward Holcroft as Charlie Hesketh, who was believed to have died in Kingsman: The Secret Service. They will be joined by new cast members Julianne Moore as the villain Poppy and Halle Berry as the head of the CIA. The sequel will move the action from London to the United States.

In Kingsman: The Golden Circle, Eggsy (Taron Egerton) and Merlin (Mark Strong) visit the U.S., where they encounter Halle Berry's character and a "swaggering, sharpshooting cowboy" called Jack, played by Pedro Pascal. The U.S. version of Kingsman is an organization known as the Statesmen, and Julianne Moore's character resides in a villainous lair known as Poppyland. Director Matthew Vaughn previously teased that the sequel will involve a skiing sequence, a barroom brawl, robot dogs, one-armed henchmen and a sequence where the protagonists have to fend off "a massive f***ing frankfurter."

Last week, a new poster teased Kingsman: The Secret Service star Colin Firth may return as Harry Hart, even though this character was presumably killed in the original. The poster featured the cryptic tagline "Reports of my death have been greatly exaggerated," a quote made famous by iconic author Mark Twain. We still don't have any exact confirmation that Colin Firth is returning to star, but director Matthew Vaughn did tease last year that he's trying to figure out a way to bring the actor back for this sequel.

Matthew Vaughn will direct from a script he co-wrote with Jane Goldman, who both wrote Kingsman: The Secret Service. The original movie was one of last year's surprise hits at the box office, taking in $128.2 million domestic and $414.3 million worldwide, from an $81 million budget. It was announced earlier this week that the Jump Street and Men in Black crossover is happening, and will be titled MIB 23. It is presumed that Channing Tatum will star alongside Jonah Hill. He will next appear in the X-Men spinoff Gambit, which has been moved out of its October release due to script rewrites. He's also set to take on the Evel Knievel biopic
