Just yesterday we reported that Elton John was in talks for the film, and there are strong hints that Colin Firth will be returning too.
There’s no news on exactly who Tatum will play, although the poster in the tweet which Channing used to announce the news (which you can see below) has many speculating that he will be part of the American version of Kingsman. While there are few plot details available, it is known that it will involve the British agents coming up against or working alongside the CIA. And if that’s who Tatum is playing, it would appear he’ll have a Southern drawl.
Shooting kicks off soon with Matthew Vaughn once more directing. It’ll be in cinemas next year.
