Director George Miller joins this week’s episode of Toolkit to talk about the making of his latest film, “Three Thousand Years of Longing.” Miller discusses the film’s place in his career as a “palate cleanser” after the high-octane “Mad Max: Fury Road,” the philosophical underpinnings of the script, and why working with actors who are also filmmakers - in this case Tilda Swinton and Idris Elba - yields the best work.
