How Jurassic World Rebirth Brought a New T-Rex to Life in Scene Cut From Jurassic Park

Approximately thirty years following the initial Jurassic Park, an extinct storyline from Michael Crichton’s 1990 novel reappears in Jurassic World Rebirth. The Delgados – consisting of patriarch Reuben (Manuel Garcia-Rulfo), his daughters Isabella (Audrina Miranda) and Teresa (Luna Blaise), and Teresa’s boyfriend Xavier (David Iacono) – encounter a harrowing ordeal when their vessel is overturned by a Mosasaur. Subsequently, they are forced to navigate through the island of Ile Saint-Hubert towards a village complex in search of assistance after being shipwrecked.

As they trace geothermal pipes towards the village, the Delgados find themselves navigating a rapid river on an inflatable raft, all the while being chased by a T-rex. This exhilarating scene is reminiscent of the novel “Jurassic Park,” where paleontologist Alan Grant finds himself in a harrowing situation, battling a T-rex in the turbulent waters alongside Tim and Lex. Interestingly, it’s revealed that Lex can’t swim during this perilous journey, as their raft dangerously approaches a waterfall.

In the 1993 movie Jurassic Park, directed by Steven Spielberg, a scene inspired by the novel was intended to depict Lex nearly drowning while rafting on a river alongside a T-rex. This harrowing sequence occurred after she managed to evade the creature’s jaws, only for her life vest to be snatched by its teeth. However, David Koepp – the writer of both Jurassic Park and Jurassic World: Rebirth – revealed in an Entertainment Weekly interview that this scene was ultimately removed due to the technical limitations of the film’s computer-generated and animatronic dinosaurs at the time.

In the year 1992, there was uncertainty if CGI could function, let alone create a swimming dinosaur. Steven Koepp pointed out that the project was already costly and with unproven technology, making it difficult. Water animation was particularly challenging back then. However, as you can observe now, those issues have been resolved.

Despite three decades of progress in Visual Effects (VFX), producing the T-rex river scene was “particularly challenging,” as stated by visual effects producer Carlos Ciudad in the special feature “Rex in the Rapids” on the digital release of Jurassic World: Rebirth. Since filming took place in Thailand, Malta, and the UK, it was necessary to shoot this sequence in three separate parts to ensure a smooth and unified appearance.

In the movie “Jurassic Dominion” of 2022, the original T-Rex character named Rexy, who was known for causing chaos in “Jurassic Park” and later appeared in all three Jurassic World films, was moved to a sanctuary. To suit its new surroundings on Ile Saint-Hubert, the filmmakers revamped the famous dinosaur’s appearance, giving it a grey and brown skin tone and naming it “Ember.

Under the guidance of director Gareth Edwards, the visual effects team made adjustments to the design of the dinosaur from the original Jurassic Park. According to visual effects supervisor David Vickery, this flexibility allows them to present a T-rex that is different from those seen in previous Jurassic films. As director Edwards explains, “Our T-rex has more pronounced eyebrows and scales around its teeth, with some shapes being slightly more simplistic and classical, reminiscent of how dinosaurs were thought to look before the Jurassic era.

Although the appearance of a T-Rex might have been modified, its distinctive, thunderous roar needed to remain untouched. As Tim Nielsen, the lead sound editor and designer, explains, ‘The T-Rex’s sound is too iconic to change entirely.’ He plans to revisit some of the original recordings from Jurassic Park, but there’s also a chance to explore fresh sounds that complement the new actions it will perform.

In 1993’s “Jurassic Park”, Rexy, the T-rex character, was unable to swim. However, this is something new for the Jurassic series, as Vickery, a VFX supervisor from “Fallen Kingdom” and “Dominion”, points out. It’s quite thrilling! There are many theories about how a T-rex might have swum, including its body position and the mechanics of swimming in such a large creature.

Mark Pascoe, the CG supervisor, carefully considered how a T-rex would behave in water following the rain-soaked Jeep scene from the initial film. As he puts it, “When you have something as large as a T-rex causing ripples in the water, it’s crucial to capture the subtleties of water movement to convincingly portray something of that size and scale.” Later, Vickery noted that the T-rex in ‘Rebirth’ is more robust and masculine, resembling the Bull T-Rex toy from 1997’s ‘The Lost World: Jurassic Park’.

Vickery notes that it’s stronger and carries a bit extra in terms of body fat. When observed powerfully cutting through the water, it seems to radiate strength and vitality, as evidenced by the turbulent water it stirs up.

Jurassic World Rebirth is now available to rent or own on digital.
