Tenet is a 2020 action-thriller and science fiction film written and directed by Christopher Nolan, who produced it with Emma Thomas. A co-production between the United Kingdom and United States, it stars John David Washington, Robert Pattinson, Elizabeth Debicki, Dimple Kapadia, Michael Caine, and Kenneth Branagh. The plot follows a secret agent (Washington) as he manipulates the flow of time to prevent World War III.

Nolan took more than five years to write the screenplay after deliberating about Tenet s central ideas for over a decade. Pre-production began in late 2018, casting in March 2019, and principal photography lasted three months in Denmark, Estonia, India, Italy, Norway, the United Kingdom, and United States, from May to November. Cinematographer Hoyte van Hoytema shot on 70 mm and IMAX. Scenes of time manipulation were filmed both backwards and forwards. Upwards of one hundred vessels and thousands of extras were used.

Delayed three times because of the COVID-19 pandemic, Tenet was released in the United Kingdom on August 26, 2020, and United States on September 3, 2020, in IMAX, 35 mm, and 70 mm. It was the first Hollywood tent-pole to open in theaters after the pandemic shutdown, and has grossed $357 million worldwide, making it the fourth-highest-grossing film of 2020, although it may not break even due to its costly production and marketing budget. Tenet received generally positive reviews from critics, who praised the visuals and production.

A CIA agent, the "Protagonist", participates in an undercover operation at a Kyiv opera house, aided by a masked soldier with a distinctive trinket, who "un-fires" a bullet through a hostile gunman. After seizing an artifact, the Protagonist is captured by mercenaries. He endures torture before consuming cyanide. He awakens to learn the cyanide was a test of his loyalty; his team has been killed and the artifact lost.
