This week on The Treatment, Elvis welcomes back director Denis Villeneuve, whose latest film is the adaptation of Frank Herbert’s “Dune,” which is nominated for nine Academy Awards, including Best Adapted Screenplay, which Villeneuve co-wrote. His other films as director include “Arrival,” “Sicario,” and “Blade Runner 2049.” Villeneuve tells The Treatment how fear weaves its way through many of his films. He talks about why his films often focus on the impact and aftermath of violence rather than the violence itself. And he says, in spite of the darkness of many of his films, he does believe that humans can evolve, and there is hope for the future.
