With the new updates from Jurassic World Rebirth featuring David Koepp and Scarlett this sounds insane. Most people think of mutant human-hybrid dinosaurs in Jurassic Park 4 but originally there was a way different story. Alan Grant and Ian Malcolm would’ve teamed up with John Hammond in a plot about the Dinos migrating onto the mainland from the islands and Keira Knightley was even in talks to star. This was a film that was rumored to have the Spinosaurus and maybe even some marine reptiles involved. Stan Winston and Spielberg were super excited but eventually this turned into the John Sayles script and that evolved into Trevorrow’s Jurassic World.
