The story is about near-immortals, The Eternals, who, along with another group called the Deviants, were created by cosmic beings called the Celestials. The Jack Kirby comic of the same name was released in 1976. There is no word on what part Jolie would portray.
Jolie can next be seen in Disney's Maleficent: Mistress of Evil, which is slated for an October 18, 2019 release.
