Marvel Studios is moving forward with The Eternals. After studio president Kevin Feige confirmed the project was in development last month, the company has now hired Matthew and Ryan Firpo to write the script. The Firpos wrote a spec script, Ruin, which topped the Black List last year and is now in preproduction.
Jack Kirby created the Eternals for Marvel when he returned to the company after a stint at DC. In the comics, the Eternals are a race of god-like humans created by Celestials, like the huge being we saw wielding the Power Stone in Guardians of the Galaxy. Knowhere, as seen in GotG and Avengers: Infinity War is the severed head of a Celestial.
The Celestials were a factor in the Infinity Gauntlet comic, so there is a chance they could appear in Avengers 4 next year to set up The Eternals. Thanos is also a descendant of the Eternals and often called an Eternal in the comics, so that is another connection that could be explored in the Marvel Cinematic Universe.
Aside from potential Avengers 4 connections (which may never come to fruition), Marvel Studios is feeling really confident in Jack Kirby concepts and visuals after putting them all over Thor: Ragnarok last year. There are no details on the specific story being told in The Eternals, but The Wrap previously reported the story will focus on Sersi.
In the comics, Sersi is 5,000-years-old and has many abilities (in addition to apparent immortality). She can teleport, reshape objects and people, shoot energy from her hands and eyes, fly, and create illusions similar to what we saw Scarlet Witch do in Avengers: Age of Ultron.
