Marvel Studios Finally Acknowledges Eternals in Sneaky Captain America 4 Trailer Scene

Chaos ensues from there, as the White House is attacked and flashes of action follow. Among those quick glimpses is Wilson soaring past a massive rocky structure, which eagle-eyed MCU fans while recognize as a major monument.

Captain America 4 Brings in Eternals’s Tiamut

The half-risen Celestial has finally been acknowledged.

The Captain America: Brave New World teaser poster features the first glimpse of Tiamut since the Earth-born Celestial erupted out of the Earth’s surface in 2021’s Eternals. Beyond that, this is the first big screen acknowledgement of the events of Eternals outside of the Eternals film itself.

The long-running rumor about Captain America: Brave New World is that Tiamut will be a point of contention for global superpowers, as countries from across the world will attempt to claim it and its resources. Among those resources will supposedly be adamantium, the fictional metal from Marvel Comics that makes up Wolverine’s skeleton.

In Eternals, the Celestial known as Arishem the Judge revealed that planets within the Marvel Cinematic Universe are essentially cocoons for Celestials themselves, and life helps them be born. Following the repopulation that Earth experienced after Avengers: Endgame brought back the missing half of the universe, Arishem declared that Earth was ready to give birth to its Celestial, Tiamut. Tiamut began to break out from the Earth’s crust but the Eternals stopped the birth before it could be complete, resulting in Tiamut’s giant hand and face being the only things visible. 

In the many MCU films since Eternals, none had acknowledged that a massive hand and face had grown out of the Earth. Now, it appears that Tiamut and the events of Eternals will be a central plot point for Wilson’s first feature film adventure as the star-spangled man.

Captain America: Brave New World hits theaters on February 14th, 2025.
