This week on The Treatment, Elvis welcomes Academy Award winning director and writer Joel Coen, whose latest film is “The Tragedy of Macbeth,” currently streaming on Apple TV+. This is Coen’s solo directorial debut. He shared the Best Director and Best Adapted Screenplay Oscars with his brother Ethan for their 2010 adaptation of  “No Country for Old Men.” Coen talks about playing with the line between theater and cinema for the adaptation of “Macbeth.” He says watching previous film adaptations of the play was helpful in determining what he did and did not want his film to be. And he talks about how casting his wife Frances McDormand and Denzel Washington as the leads led to a small but significant change in the story.
