Watch new trailer for Marvel Studios' 'Eternals'

Marvel Studios has released an action-packed new trailer for Oscar-winning director Chloe Zhao's "Eternals."

Apart from eye-popping visuals, the trailer details the movie's plot, and answers a question those who don't read comic books may have been wondering: "Who are the Eternals?"

The trailer explains that the super-powerful figures were created 7,000 years ago by god-like characters known as The Celestials.

If you've just seen the Marvel movies, Kurt Russell played the Celestial Ego in "Guardians of the Galaxy Vol. 2," and another -- seen in the new trailer -- Eson the Searcher, was shown laying waste to a planet in the first "Guardians" film.

The new footage clarifies the Eternals were created to protect Earth from an alien menace known as The Deviants.

"Why didn't you guys help fight Thanos...or all the other terrible things throughout history?" Kit Harington's hero Black Knight sarcastically asks Gemma Chan's Eternal Sersei. "We were instructed not to interfere...unless Deviants were involved," she responds.

Salma Hayek's Ajak explains that the Avengers' victory at the end of "Endgame" -- bringing back all the lives that Thanos had snapped away -- created The Emergence, an awakening of The Deviants, that will destroy the planet unless The Eternals reunite from all over the globe to stop them.

"How long do we have?" Richard Madden's Ikaris asks. "Seven days," Ajak replies.

"We've loved these people since the day we arrived," Angelina Jolie's Thena says in voice-over. "When you love something, you protect it."

"You can't protect any of them," replies the Deviant leader Kro, to a captured Thena.

The footage also shows the other Eternals -- including Barry Keoghan's Druig, Kumail Nanjiani's Kingo, Brian Tyree Henry's Phastos, Ma Dong-seok's Gilgamesh, Lauren Ridloff's Mikari, and Lia McHugh's Sprite -- using their respective powers to combat the threat.

For all its apocalyptic scope, the trailer also injects some humor, ending with a hook featuring some of the reunited heroes sitting around a table.

"I bet you've built the perfect safehouse," Madden's character comments, gesturing to the table. "What's this even made of, vibranium?" He then smashes it in two, mistakenly thinking it's the unbreakable Wakandan metal.

"Fall Collection: IKEA," an exasperated Phastos replies.

Marvel Studios' "The Eternals" opens Nov. 5.

Marvel Studios is owned by Disney, the parent company of ABC News.
