Film4′s film adaptation of the Shakespeare classic has Snowtown helmer Justin Kurzel attached to direct. Project is glued together by a number of prior relationships. Michael Fassbender is attached to play the iconic title antihero, with Natalie Portman attached to play his scheming Lady Macbeth. The pair recently filmed Terrence Malick’s untitled Austin-set pic together. Script is by Todd Luiso and Jacob Koskoff, who previously teamed up on 2009′s The Marc Pease Experience. Fassbender’s Shame producers Iaian Canning and Emile Sherman, whose UK-Australia See-Saw banner also produced The King’s Speech, are producing with Film4. Sherman had a hand in financing Kurzel’s feature debut Snowtown (AKA The Snowtown Murders). Kurzel, Fassbender, and Portman are repped by CAA.
