The first trailer for Christopher Nolan’s Tenet, a movie set within the world of international espionage, has made its way online, giving a taste of the mysterious filmmaker’s next project. The first trailer sheds some light on the story line, which has been kept under wraps for quite some time. It seems like John David Washington’s character is trying to prevent a third World War, but it’s unclear what that entails. Tenet is Nolan’s follow-up to his Oscar-nominated war drama Dunkirk and features a star-studded cast of John David Washington, Robert Pattinson, Elizabeth Debicki, Kenneth Branagh, Michael Caine, Dimple Kapadia, Aaron Taylor-Johnson and Clemence Poesy. Unlike Dunkirk, Nolan’s 2017 film about the heroic rescue mission that took place in Dunkirk, France, during the Second World War, Tenet has more in common with Nolan’s previous films. There are elements of Inception, the director’s critically acclaimed and beloved heist-within-dreams film from 2010, and wisps of Memento. Warner Bros. is also releasing a longer prologue for the film, which will play before Star Wars: The Rise of Skywalker in certain IMAX theaters. Warner Bros. opens Tenet July 17, 2020.
