<P> Trevorrow said the film's dinosaurs would be "a parable of the treatment animals receive today: the abuse, medical experimentation, pets, having wild animals in zoos like prisons, the use the military has made of them, animals as weapons ." The idea of weaponized dinosaurs came from Spielberg . Trevorrow said that with the film's dinosaur auction, "The worst instincts of mankind are revealed . The first film was very clearly about corporate greed . This is just about human greed ." The film includes ideas previously featured in a rejected 2004 draft for Jurassic Park IV (later Jurassic World), presented in the same structure: a return to Isla Nublar followed by a second half set in a large Gothic building on the mainland . The idea of a dinosaur auction was also present in the rejected draft, which Trevorrow had read while writing the first Jurassic World film . </P> <P> Bayona had his own ideas incorporated into the script while essentially retaining the same original story devised by Trevorrow and Connolly . The film's underwater opening sequence was already in Trevorrow and Connolly's script, and Bayona asked Trevorrow to push for it to become a bigger scene with a larger set . Among Trevorrow's ideas was to include Jeff Goldblum's character of Ian Malcolm, who appeared in the franchise's earlier films . Trevorrow and Goldblum discussed dialogue ideas for Malcolm, and Trevorrow stated that he used a lot of dialogue from Crichton's Jurassic Park novel for the character . Marshall stated that Trevorrow wrote Malcolm as "the' Uh oh, danger, I told you so' kind of character," and Trevorrow said about the character, "I saw him as kind of Al Gore . He's got a beard now, and he's like,' I told all of you this was going to be a disaster, and sure enough it is ."' Bayona and Trevorrow ultimately removed certain moments from the script that they felt would be better for the sequel, which was expected to depict dinosaurs having spread around the world . </P> <P> In October 2016, casting was underway for the role of a nine - year - old girl . Approximately 2,500 girls were interviewed for the role, which ultimately went to Isabella Sermon, marking her film debut . By November 2016, Tom Holland--who previously starred in The Impossible--had discussed having a possible role in the film, but he did not believe he would be available for filming because of scheduling conflicts . Toby Jones, Rafe Spall, and Justice Smith were cast at the end of the year . </P> <P> Daniella Pineda, Ted Levine and James Cromwell were cast in early 2017, while Wong confirmed his return as Dr. Henry Wu . To maintain secrecy, the Ancient Futures title was used in the casting phase . During auditions, references to dinosaurs were replaced with animals such as lions and grizzly bears . To convince the studio that Pineda was right for the role of Zia, Bayona had her demonstrate that she could perform comedy and drama scenes, as well as improvisation . Pineda auditioned a total of seven times before receiving the role . She auditioned for Bayona, Atienza, and Crowley, and did not meet the cast until she arrived in England for filming . </P>
