Tenet is a 2020 science fiction action-thriller 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 film follows a secret agent who learns to manipulate the flow of time to prevent an attack from the future that threatens to annihilate the present world.
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 took place in March 2019, and principal photography lasted six months, from May to November, in Denmark, Estonia, India, Italy, Norway, the United Kingdom, and the United States. Cinematographer Hoyte van Hoytema shot on 70 mm and IMAX. Scenes of time manipulation were filmed both backwards and forwards. Over 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 grossed $363 million worldwide, making it the fifth-highest-grossing film of 2020. However, it failed to break even against its high production and marketing budget due to the limited theatrical release during the pandemic. The film received generally positive reviews, with praise towards the action sequences, visuals, musical score, cinematography and performances, while the story and sound mixing received some criticism. The film received nominations for Best Production Design and Best Visual Effects at the 93rd Academy Awards.
