Big-budget blockbusters are often built on shifting sand. Scripts are tweaked on the fly, storylines morph during post, and entire endings get rewritten just before the final cut. Jurassic World Rebirth was no exception.

Jurassic World Rebirth is the latest reboot of the beloved franchise. This time around Scarlett Johansson, Mahershala Ali, and Jonathan Bailey head to a fresh island of mutant dinosaurs, where they experience a familiar mix of splashy kills and not-so-subtle morality tales.

That remains true in “Jurassic World Rebirth,” though at this point in the story, public interest in any dinosaurs has waned considerably. So, in the new film, there is simply an island near the equator where the remaining dinosaurs live — it’s literally the only place with a climate they can survive.
