Jurassic World 4: Rebirth (2025) takes place several years after the events of Jurassic World: Dominion, where dinosaurs now coexist with humans around the world. However, this delicate balance is soon disrupted by a new and more sinister force: Genomex, a corporation with plans that threaten to reshape the world in unimaginable ways. Unlike previous villains, Genomex’s goals go far beyond cloning dinosaurs—they aim to merge dinosaur DNA with human genomes, creating hybrid creatures that are not only more intelligent but also far deadlier.

The film begins with Owen Grady (Chris Pratt) and Claire Dearing (Bryce Dallas Howard) living in a secluded sanctuary designed to provide a safe haven for dinosaurs. They’re focused on keeping the peace between humans and dinosaurs while raising Maisie Lockwood (Isabella Sermon), the genetically engineered clone of Charlotte Lockwood, whom they’ve adopted. Their peaceful existence is shattered when a new experiment from Genomex, a hybrid dinosaur-human creature, escapes from a high-security facility.

Joining the cast is Scarlett Johansson as Dr. Elara Vaughn, a brilliant geneticist and former associate of Dr. Wu (BD Wong). Initially complicit in Genomex’s hybrid program, Dr. Vaughn becomes horrified by the monsters she helped create. She warns Owen and Claire about Genomex’s plan to mass-produce these hybrids for military and commercial purposes, and joins their mission to stop the impending disaster.

As they race against time, Owen, Claire, and Dr. Vaughn face terrifying new hybrids: dinosaur-human hybrids with intelligence, tactical thinking, and the ability to communicate. Among them is “Reximus,” a hybrid fusion of a T. rex and human DNA, towering over 12 feet tall, combining deadly agility, intelligence, and brute strength. Reximus becomes the film’s primary antagonist, making the stakes even higher.

The film’s intense climax unfolds in Genomex’s secret facility, where a full-scale battle erupts between humans, dinosaurs, and the hybrids. The movie leaves audiences with a chilling question: can humanity ever truly coexist with creatures that are no longer just animals, but also part human?
