Interesting quote from the director regarding he Hybrid-Dino.
"Yes, there will be one new dinosaur created by the park’s geneticists. The gaps in her sequence were filled with DNA from other species, much like the genome in the first film was completed with frog DNA. This creation exists to fulfill a corporate mandate—they want something bigger, louder, with more teeth. And that’s what they get. I know the idea of a modified dinosaur put a lot of fans on red alert, and I understand it. But we aren’t doing anything here that Crichton didn’t suggest in his novels. This animal is not a mutant freak. It doesn’t have a snake’s head or octopus tentacles. It’s a dinosaur, created in the same way the others were, but now the genetics have gone to the next level. For me, it’s a natural evolution of the technology introduced in the first film. Maybe it sounds crazy, but most of my favorite movies sound crazy when you describe them in a single sentence. … We’re trying to tell a bold new story that doesn’t rely on a proven formula, because the movies we watch over and over again are the ones that surprised us, that worked when they shouldn’t have. I understand the risks of leaving the safe zone. We’ve all been disappointed by new installments of the stories we love. But with all this talk of filmmakers “ruining our childhood”, we forget that right now is someone else’s childhood. This is their time. And I have to build something that can take them to the same place those earlier films took us. It may not happen in the same way everyone expects it to, but it’s the way I believe it needs to happen."
