Tenet is a 2020 science fiction action thriller film written and directed by Christopher Nolan, who also produced it with his wife Emma Thomas. It stars John David Washington, Robert Pattinson, Elizabeth Debicki, Dimple Kapadia, Michael Caine, and Kenneth Branagh. The film follows a former CIA agent who is recruited into a secret organization, tasked with tracing the origin of objects that are traveling backward through time and their connection to an attack from the future to the present.

Nolan took over five years to write the screenplay after deliberating about Tenet's central ideas for more than a decade. Pre-production began in late 2018, casting took place in March 2019, and principal photography lasted six months in multiple countries. After delays due to the COVID-19 pandemic, Tenet was released in the United Kingdom on August 26, 2020, and in the United States on September 3, 2020. It was Nolan's last film to be released by Warner Bros. Pictures.

Tenet was the first Hollywood tent-pole to open in theaters during the pandemic and grossed $365 million worldwide on a $205 million budget, making it the fifth-highest-grossing film of 2020 despite failing to break-even. The film divided critics but won Best Visual Effects at the 93rd Academy Awards and received numerous other accolades.
