After Michael Fassbender buzzed up fall fests with his perf in Steve McQueen’s “Shame,” the thesp is again joining the helmer on his next project, “Twelve Years a Slave.”McQueen will direct from a script he co-wrote with John Ridley. Pic also stars Chiwetel Ejiofor and tells the true story of Solomon Northup, a New York citizen who was kidnapped in Washington in 1841 and rescued from a cotton plantation in Louisiana in 1853. Plan B’s Dede Gardner and Jeremy Kleiner are set to produce the film, which is expected to start production early next year. CAA is arranging financing for the pic and representing U.S. rights. Fassbender appeared in “Hunger,” the first pic helmed by visual artist McQueen, as well as “Shame.” Both were released in the U.S. by Fox Searchlight. While the German-Irish thesp’s profile has risen with starring roles in the Fox tentpole “X-Men: First Class” and next summer’s “Prometheus,” Fassbender continues to appear in smaller films: Earlier this year, he starred alongside Mia Wasikowska in “Jane Eyre” and can be seen later this fall in both “Shame” and Sony Pictures Classics’ David Cronenberg pic “A Dangerous Method” as Carl Jung. He is repped by CAA.
