After waiting for over twenty years, audiences around the globe are now just days away from returning to Isla Nublar, the island from the original Jurassic Park. John Hammond’s dream has become a reality and a theme park filled with long extinct dinosaurs is officially open to the public. After a successful decade, the owners of Jurassic World push the boundaries of science even further by creating a transgenic dinosaur unlike any to ever roam the Earth.

Though Chris Pratt, Bryce Dallas Howard and Vincent D’Onofrio are sure to impress in the film, the real stars of Jurassic World are the dinosaurs themselves. Led by the vicious Indominus Rex, the dinosaurs in the park break free to attack the crowds of tourists on the island. The man partially responsible for the creature’s creation, as well as advising on all of the dinosaurs, is also one of the few people to work on all four of the Jurassic Park films: paleontologist Dr. Jack Horner.

The above featurette spotlights Horner and his involvement in the creation of Indominus Rex. The real-life Alan Grant shows off some of his knowledge in the video as well as conveying his overall passion for dinosaurs. Director Colin Trevorrow also appears, emphasizing the importance of Horner’s knowledge on the set.

Horner recently revealed that the science in Jurassic World used to create the hybrid dinosaur actually exists. In fact, he specifically states that the science behind Indominus Rex is more plausible than the idea of bringing back existing dinosaurs. Utilizing his knowledge has allowed the film to move from impossible science fiction to an improbable possibility, grounding the story and making the horror on screen more palpable.

The final Jurassic World trailer revealed the film’s darker tones. The lighthearted sense of humor and the nostalgia of previous trailers has been removed. The human characters are no longer joking or proud of their accomplishments.  Instead, the trailer capitalizes on the terror the dinosaurs bring and the nearly unstoppable might of the primary antagonist Indominus Rex.

Jurassic World will live and die by its portrayal of the dinosaurs. The film has to capture the raw power of the creatures exemplified by the T-Rex in the first Jurassic Park. At the end of the day, that is what audiences are going to remember. If the film succeeds in that regard, it will be thanks in no small part to Dr. Horner’s work on the film.

Jurassic World opens in U.S. theaters June 12, 2015.
