Warner Bros. Pictures has unveiled tv spot for Tenet (2020). 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. Watch tv spot now!
