Jurassic World director Colin Trevorrow has opened up about the film’s Tyrannosaurus Rex and the information is incredibly badass! In an interview with Slashfilm, Trevorrow explains that the T. Rex we see in the film isn’t a brand new dinosaur. Rather, it’s the same one from Jurassic Park, the one that injured Dr. Ian Malcolm (Jeff Goldblum)!
He explains:
She is 22 years older. But she’s not limping around. …it’s going to move a little bit differently, but it’ll move differently because it’s older. And we’re giving her some scars and we’re tightening her skin. So, she has that feeling of, like, an older Burt Lancaster. And this movie is her Unforgiven.
