Ramin Setoodeh Executive EditorAfter two movies, Channing Tatum thought he was done playing Magic Mike. But he’ll take one more swing around the stripper’s pole in “Magic Mike’s Last Dance,” which begins shooting in London in March.In this week’s issue of Variety, Tatum talks about taking a four-year hiatus from acting to produce TV shows and movies with Free Association, the company that he launched in 2014 with his producing partner Reid Carolin. One of the company’s most anticipated projects is “Magic Mike’s Last Dance,” the third and (supposedly) final movie in the franchise that was inspired by Tatum’s days as an exotic dancer.The film, which will be directed by Steven Soderbergh from a script written by Carolin, will premiere on HBO Max.
