It hasn't been a secret that Universal Pictures and Amblin Entertainment have been trying to make a Jurassic Park 4. Nor is it a secret that way back in 2005 they were tinkering around with a JP4 story that would have seen cloned dinosaurs created with a mixture of human DNA, thus giving us terrifying new creatures that were part dinosaur and part human.
I hope someone else makes this concept into a film.
I find that first sculpt more terrifying than any dinosaur.
