Made off a reported budget of over $200 million, Tenet follows a secret agent and his allies fighting to prevent World War III and the triggering of something worse than a nuclear holocaust. Their mission won’t involve full-fledged time travel, but rather a strange phenomenon known as time inversion. The cast includes John David Washington, Robert Pattinson, Elizabeth Debicki, Michael Caine, Kenneth Branagh, Dimple Kapadia and Aaron Taylor-Johnson, among others.
