From The Attic Dwellers’ YouTube description: The first major post-Avengers: Endgame installment in the Marvel Comic Universe has already started casting. The Eternals is reportedly eyeing Angelina Jolie, Kumail Nanjiani, and Richard Madden for starring roles. It’s even been rumored that Keanu Reeves will play the villain in the movie!!!
The Eternals are a fictional species of humanity appearing in American comic books created by Jack Kirby for Marvel Comics. They are described as an offshoot of the evolutionary process that created sentient life on Earth.
When the Celestials visited Earth five million years ago and performed genetic experiments on early proto-humanity, they created two divergent races: the long-lived Eternals, and the genetically unstable and monstrously grotesque Deviants.
