Here at GAMbIT we try to avoid trafficking in rumors or conjecture. That said, this comes from JoBlo, and everyone over there is pretty on top of their shit. Take this with a grain of salt, but supposedly the plot of Jurassic World goes a little something like this:
They splice together a T-Rex, raptor, snake, and cuttlefish to create a monstrous new dino that, of course, gets loose and terrorizes the park.
…there will be lots of Dino on Dino fighting, as some of the Dinos are “good guys” that are trained by Chris Pratt’s character. The raptors and T-Rex are among the “trained” good dinosaurs. The big bad dinosaur has instant camouflage abilities, like the cuttlefish, so he blends into the background, is smart like the velociraptor, uses his jaw like a snake, and can terrorize like the T-Rex.
Oh my god I hope this is true. It’s like director Colin Trevorrow took a look at the script and said “It’s good, but…can we make it crazier?”
