When a franchise as big as Jurassic World announces a new film, the first question is always: who’s in? For Jurassic World Rebirth, the answer is a complete overhaul — none of the familiar faces from the previous trilogy return. Instead, the 2025 installment introduces a fresh ensemble led by Scarlett Johansson, Mahershala Ali, and Jonathan Bailey.

Why is Chris Pratt not in Jurassic World Rebirth?

Chris Pratt’s previous role in Jurassic World

  • Chris Pratt played Owen Grady in all three Jurassic World films (IMDb)
  • Owen Grady was the lead human character, a Velociraptor trainer and park employee (Wikipedia)

Reasons for his absence

  • Multiple 2025 reports confirm Chris Pratt is not part of the Jurassic World Rebirth cast (Marca)
  • A February 2025 report noted there was no indication he would appear, though it left open the possibility of a cameo or post-credits appearance (MSN)

Reactions from the cast and crew

  • The film is widely presented as a fresh ensemble rather than a continuation centered on Owen Grady (Marca)
  • Director Gareth Edwards commented that the new cast brings a different energy, according to press coverage (NBC Insider)
The trade-off

Losing a star like Chris Pratt means the studio bets entirely on name recognition of Johansson, Ali, and Bailey — a high-risk, high-reward strategy for a franchise that grossed over $6 billion.

The implication: by removing the Owen Grady anchor, the filmmakers signal that Rebirth is not a direct sequel but a soft reboot, allowing new audiences to jump in without backstory.

Did they change the cast in Jurassic World Rebirth?

New cast members and their roles

  • Scarlett Johansson stars as Zora Bennett, described as a skilled mercenary (official site)
  • Mahershala Ali plays Duncan Kincaid, a tactical expert (official site)
  • Jonathan Bailey plays Dr. Henry Loomis, a paleontologist (official site)
  • Rupert Friend plays Martin Krebs, a corporate representative (official site)
  • Manuel Garcia-Rulfo plays Reuben Delgado, a family man caught in the events (official site)

Returning actors from previous Jurassic World films

  • No actors from the original Jurassic World trilogy reprise their roles in Rebirth (Marca)
  • This includes Chris Pratt (Owen Grady), Bryce Dallas Howard (Claire Dearing), and Jeff Goldblum (Ian Malcolm) (Wikipedia)

How the cast compares to Jurassic World: Dominion

  • Dominion had a sprawling ensemble of over 20 returning characters; Rebirth caps the main cast at six (IMDb)
  • The new team is described as a group of experts on a single mission, not a multi-threaded narrative (NBC Insider)

The pattern: reducing the cast size lets the film focus on character dynamics within a tighter plot, avoiding the sprawl that critics noted in Dominion.

Is anyone from Jurassic World in Rebirth?

List of returning characters

  • No characters from the Jurassic World trilogy appear in Rebirth (Marca)
  • Even minor characters like Barry (Omar Sy) or Zia (Daniella Pineda) are absent (Wikipedia)

Why the studio chose a fresh cast

  • The film is set years after the events of Dominion, allowing a new story line with new protagonists (official site)
  • Director Gareth Edwards and writer David Koepp aimed to create a standalone entry that doesn’t require prior knowledge (NBC Insider)

Connections to the franchise’s lore

  • The film still references the original InGen incidents and the abandoned research facility on Isla Sorna (official site)
  • Familiar dinosaur species like T. rex and Velociraptor appear, but the human cast is entirely new (Fandango)
Why this matters

For longtime fans, the absence of any touchstone characters means the emotional weight rests entirely on the new ensemble. The film’s success hinges on whether audiences embrace Johansson, Ali, and Bailey as the new face of the franchise.

The catch: reboot without nostalgia is a gamble — but it also frees the story from the baggage of a 30-year timeline.

Who is LGBTQ in Jurassic Park?

LGBTQ characters in the Jurassic Park franchise

  • Sammy Gutierrez from Jurassic World: Camp Cretaceous is a confirmed LGBTQ character (NBC Insider)
  • The franchise has otherwise featured few explicitly LGBTQ characters in its main films (Wikipedia)

Sammy Gutierrez’s role in Jurassic World: Camp Cretaceous

  • Sammy is a teenager who works on the dinosaur reserve and is shown to have a crush on another girl, Yaz (NBC Insider)
  • Her storyline was praised for natural representation without being a “very special episode” (Marca)

Confirmation of LGBTQ representation in Rebirth

  • No LGBTQ characters have been announced for Jurassic World Rebirth as of July 2025 (official site)
  • The cast list does not include any openly LGBTQ actors or characters, but future announcements are possible (IMDb)

The pattern: the franchise has moved toward inclusion in its animated series, but the live-action films have been slower to follow. Rebirth’s silence on the matter leaves room for either a deliberate choice or a missed opportunity.

Why Jurassic World Rebirth changed its original ending?

Original ending details

  • The original ending was reportedly considered a “cop-out” by the studio (MSN)
  • Early drafts had a rescue mission that resolved too neatly without consequences (Marca)

What changed and why

  • The film’s ending was rewritten to be more impactful, involving a moral dilemma for the main characters (NBC Insider)
  • Cast members were reportedly involved in the decision to push for a darker resolution (MSN)
