Eternals is a 2021 American superhero film based on the Marvel Comics race of the same name. Produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures, it is the 26th film in the Marvel Cinematic Universe (MCU). The film was directed by Chloé Zhao, who wrote the screenplay with Patrick Burleigh, Ryan Firpo, and Kaz Firpo. It stars an ensemble cast including Gemma Chan, Richard Madden, Kumail Nanjiani, Lia McHugh, Brian Tyree Henry, Lauren Ridloff, Barry Keoghan, Don Lee, Harish Patel, Kit Harington, Salma Hayek, and Angelina Jolie. In the film, the Eternals, an immortal alien race, emerge from hiding after thousands of years to protect Earth from their evil counterparts, the Deviants.

 In April 2018, Marvel Studios president Kevin Feige announced that a film based on the Eternals had begun development, with Ryan and Kaz Firpo hired to write the script in May. Zhao was set to direct the film by late September, and was given significant creative freedom with the film, which resulted in filming on location more than previous MCU films. Zhao re-wrote the screenplay, which Burleigh was later reported to have also contributed to. Principal photography took place from July 2019 to February 2020, at Pinewood Studios as well as on location in London and Oxford, England, and in the Canary Islands.  

Eternals premiered in Los Angeles on October 18, 2021, and was released theatrically in the United States on November 5, as part of Phase Four of the MCU. The film has grossed over $161 million worldwide. It received mixed reviews from critics, with praise centering on its themes and visuals, and criticism aimed at its exposition, pacing, runtime, and lack of character development.
