We saw Jurassic World Rebirth on opening day, but haven't discussed it with each other yet. We share all our favorite moments, dinosaurs, and theories about the movie.

For all of our fun facts and other details go to https://iknowdino.com/-Episode-543/

In this episode, we break down the horror-infused tone of Jurassic World: Rebirth, from malfunctioning park systems to scary Mosasaurus sequences. We explore standout scenes like Bronto Billy’s first appearance in NYC, the Quetzalcoatlus and Spinosaurus teaming up with the Mosasaur. We give our thoughts on the all new cast including Scarlett Johansson (Zora Bennett), Mahershala Ali (Duncan Kincaid), Jonathan Bailey (Dr. Henry Loomis), and other minor characters.

We also dive into updated animal portrayals—like the adorable backpack-sized Aquilops named Dolores, the eerie hybrid Mutadon, and the menacing Distortus rex—along with practical effects and callbacks to earlier films. Finally, we debate what worked, what didn’t, favorite dinos, and lingering questions about the sequel’s direction.
