Laura Dern, Jeff Goldblum, and Sam Neill are reprising their roles from Steven Spielberg's "Jurassic Park" franchise in "Jurassic World 3" and fans cannot be more excited.

Director Colin Trevorrow confirmed the return of the original "Jurassic Park" cast during a Collider-hosted screening of "Jurassic World" on Tuesday. The event took place at the ArcLight Cinemas in Hollywood. According to the publication, all three actors have "sizable roles in the sequel," but did not provide further details.

Dern was at the event to personally confirm her involvement in the film. Trevorrow brought the actress out after a fan from the audience asked him if the original cast was coming back. It was a surprise for everyone at the screening.

"I'm so excited to have to share this with all of you..I love dinosaurs, I love that you love the life we do," Dern said on stage.

The "Twin Peaks" star also did the honours and brought Neill and Goldberg out to the stage.

"If i'm not asking too much...I'd just like to bring my friends Sam Neill and Jeff Goldberg,
Dern continued.

Trevorrow confirmed that the actors would have "major roles" in "Jurassic World 3." This time, Dern does not have a cameo but major appearance in the film.
