Zoe Saldaña has revealed how she feels about the upcoming release of "Avatar: The Way of Water," which is happening 13 years after the first movie came out.

"It's exciting; nerve-wracking," Saldaña, who plays Neytiri in the franchise, told Entertainment Weekly in an interview published Tuesday. "Humbling as well, you know — the wait is finally over. And we get to share something that we love so much with so many people that we know love it, too."

The 43-year-old actress also explained that playing Neytiri in "Avatar" is different from portraying Gamora in various Marvel movies including "Guardians of the Galaxy."

"They demand a different kind of sacrifice, but they stand very unique on their own subjective grounds," Saldaña said. "Gamora is a much more traditional approach where you wake up at 3 o'clock in the morning and you go through the whole prosthetic process."

Playing Neytiri, according to the actress, is more of a "practice" as it required months of training with movement coaches, traveling to the jungle and making her own food.

"And once you use all of that, you do bring it into what we call the volume, which is the set, when you shoot under performance-capture," she added. "This world has to become alive in your imagination."

The actress then shared director James Cameron's vision, saying, "He's showing you a very rough version of what the environment looks like. But you have been prepping yourself so much, and you believe so much in Pandora that it's just not a difficult journey for you to make."

"Avatar: The Way of Water" will hit theaters on Dec. 16. Ahead of its premiere, the original "Avatar" movie with remastered audio and sound will be released globally on Sept. 23.

The Twitter handle of "Avatar" unveiled the upcoming installment's official title on April 28.

It also confirmed that the teaser trailer of the highly anticipated movie will be shown in theaters ahead of Marvel's "Doctor Strange in the Multiverse of Madness," which is slated for release Friday.
