The three main stars of the original "Jurassic Park" will return for "Jurassic World 3."

While Jeff Goldblum's suave mathematician Dr. Ian Malcolm teamed up with the stars of the new "Jurassic" films, Chris Pratt and Bryce Dallas Howard, in "Jurassic World: Fallen Kingdom," Sam Neill and Laura Dern have also signed on for the third installment.

The film's official Instagram account posted a photo of the trio, with the caption, "They’re back. Welcome to Jurassic World Alan Grant, Ellie Sattler & Ian Malcolm. #2021."

The pair will reportedly reprise their respective roles of paleontologist Dr. Alan Grant and paleobotanist Dr. Ellie Sattler for the first time since 2001’s "Jurassic Park III."

Again directed by "Jurassic World" series filmmaker Colin Trevorrow, "Jurassic World 3" is set to start production early next year.

Dern shared a photo with Trevorrow, announcing the exciting news.

"Loved joining my buddy, Colin, to announce the return of the original cast of Jurassic Park back into the Jurassic World," she said in the caption.

In the new teaser, "Jurassic World: Battle at Big Rock," dinosaurs from the rebooted theme park have escaped their confines and are menacing the mainland.
