"[They're] a group of immortals who have been on Earth for 35,000 years. They've been there amongst the MCU," said Marvel Studios president Kevin Feige earlier this summer at San Diego Comic-Con.



The Jack Kirby comic introduces three different groups of beings that were created by celestial Gods: the Deviants (a group that was constantly at war), humans, and the immortal Eternals, of which there are more than 30.

Harington's character isn't an Eternal. Instead, Whitman becomes a hero known as Black Knight.

In the film, Harington will reunite with his former "Game of Thrones" costar, Richard Madden, who was announced to play Ikaris, one of the leaders of the Eternals.
