Steven Soderbergh directed the first movie, Magic Mike in 2012 which starred Tatum and Matthew McConaughey and took just over £8 Million in the UK.
There was a sequel in 2015, Magic Mike XXL, which was directed by Gregory Jacobs and although McConaughey didn't return Tatum did, the movie took £6 Million in the UK.
This means this movie will most like complete a trilogy, and maybe we'll get McConaughey back even if for a cameo.
The movie is being written by Reid Carolin as showing in the script cover in the Tweet.
No more information is given other than by the looks of things it will be released on HBO Max as well as the possibility of a theatrical release.
