Marvel's "Eternals" has released a new final trailer that promises a breathtaking epic from Oscar-winning director Chloe Zhao.

The Eternals, immortal aliens created by the Celestials, have secretly lived on Earth for thousands of years to protect humanity from the evil Deviant. At some point the Eternals disbanded, but were reunited after the events of The Avengers: After the events of Endgame, they reunite to once again fight the Deviant.

Aside from the A-list cast and director, not much is known about the plot of Eternals or its connection to other films in the MCU. Along with Shang Chi and The Legend of the Ten Rings, it heralds the arrival of Phase 4 on the film front (along with a ton of Disney Plus series).

Here is what we know so far about Eternals.

Watch "Eternals" online at Disney Plus soon.

On Friday, December 10, Disney Plus announced in a press email that "Eternals" will be available on Disney Plus on January 12, 2022. The film was released on November 5, 2021.

Like other MCU films, "Eternals" was delayed due to the coronavirus pandemic. It was originally scheduled to be released in November 2020.

We are tracking all the news and leaks regarding the post-credit scenes for "Eternals," which Marvel has wrapped up ever more tightly; one scene has leaked to some extent, but we know absolutely nothing about the other, and we are still waiting to see how the film will turn out.

The latest and last trailer for The Eternals begins with Salma Hayek riding a horse to meet Richard Madden. She tells how Thanos wiped out half the universe and the return of all its people created the energy that made possible the cataclysm known as "Emergence." Now they must reunite their fellow Eternals to save humanity from extinction.

The first official "clip" from "Eternals" shows the heroes fighting off a band of Deviant Monsters terrorizing the people of Earth. The clip features Kumail Nanjiani's Khingo, Lauren Ridloff's Makkari, and Richard Madden's Ikaris, with Khingo blowing bolts out of his fingers.

At the end of the clip, Kingo and Makkari communicate in ASL.

The first trailer gave a glimpse of how Eternal lives up to its name and spreads across generations and continents.

Marvel also previously gave us a little sneak peak in the mega-preview of the upcoming film.

Starting at 2:20 in the video below, Salma Hayek rides a horse and says in voiceover, "When you love something, you fight for it." From there, the video shows fragments of sword-wielding Angelina Jolie, Richard Madden leading the group, and a jacked-up Kumail Nanjiani, who coolly removes his sunglasses.

The cast of "Eternals" is stellar, to say the least. And it marks the reunion of two of the stars of "Game of Thrones". Here is the lineup:

Angelina Jolie as Senna: Eternal, a fierce warrior who can create any weapon from cosmic energy.

Salma Hayek as Ajak: the wise and spiritual leader of the Eternal, with healing abilities. He can communicate with the Celestials.

Richard Madden as Ikaris: Tactical leader of the Eternals who flies, projects cosmic energy beams from his eyes, and has superhuman strength.

Kumail Nanjiani as Khingo: Eternals who can project cosmic energy from their hands. He becomes a popular Bollywood movie star in order to blend in on Earth.

Gemma Chan as Selsey: Eternal who has an affinity for humanity and can manipulate matter. She has loved Icaris for centuries and poses as a museum curator on Earth.

Lauren Ridloff (as McCully): an Eternal with cosmic powers who scouts planets at super-speed; the first deaf superhero in MCU productions; she is also the first deaf superhero in the MCU.

Brian Tyree Henry as Fastus: Eternal inventor who secretly helps mankind make technological advances; the first superhero portrayed as gay in an MCU film.

Don Lee as Gilgamesh: The most powerful Eternal who can project an exoskeleton of cosmic energy. Thena's partner.

Leah McHugh as Sprite: Eternal who can project realistic illusions and looks like a 12 year old kid.

Barry Keoghan as Druig: An Eternal who can use cosmic energy to control the minds of others. He becomes distant from other Eternals because of his opposition to interaction between other Eternals and humanity.

Kit Harrington as Dane Whitman: A human warrior who wields a mystical sword.

According to the comics, the Eternals derive from a popular mythology dating back to the dawn of mankind. An ancient overseer known as the Celestials arrived on Earth and divided its inhabitants into three sects.

The Deviants were indeed a great threat, but the Eternals were also their own greatest enemies. A civil war erupted between them long ago, splitting them into two groups, one led by Kronos and the other by Uranos. Kronos and the "good guys" were victorious and remained on Earth, while Uranos and his followers were banished to Titan.

Deviant is expected to be the villain in this film.

Now, Titan should sound familiar to anyone who followed the story of Thanos from the first to the third MCU. Yes, Thanos is an Eternal, born to the leader of the Titans.

Unlike the Titans, the Eternals on Earth look like humans.
