John David Washington is the new Protagonist in Christopher Nolan’s original sci-fi action spectacle “Tenet.” Armed with only one word—Tenet—and fighting for the survival of the entire world, the Protagonist journeys through a twilight world of international espionage on a mission that will unfold in something beyond real time. Not time travel. Inversion. The international cast of “Tenet” also includes Robert Pattinson, Elizabeth Debicki, Dimple Kapadia, Martin Donovan, Fiona Dourif, Yuri Kolokolnikov, Himesh Patel, Clémence Poésy, Aaron Taylor-Johnson, with Michael Caine and Kenneth Branagh.
