The Jurassic Park films are all about bringing the past to life. While the films' in-universe scientists take that idea literally and resurrect long-extinct species, the movies themselves love to make allusions to older entries in the series. These movies are crammed with enough self-referential callbacks to fill a brachiosaurus.
Jurassic World: Fallen Kingdom follows this trend, and it'll take more than a single viewing to catch all of the Fallen Kingdom Easter eggs you definitely missed the first time around. Even die-hard fans who know their Jurassic Park trivia might overlook these homages and Easter eggs.
Although Jurassic World is a little heavier on the nods to past films - and blatant product placement - Fallen Kingdom likes to pay homage to its roots, too. Whether that means reaching all the way back to a year time forgot (1993) or examining the mistakes of its predecessor, Fallen Kingdom hides enough in its frames to reward repeat viewings. That is, if the constant explosions and wild dinosaurs aren't enough on their own.
Spoilers for Jurassic World: Fallen Kingdom ahead.
Claire moves from a strictly capitalistic view of the dinosaurs to a more compassionate one in Fallen Kingdom. To illustrate this point, she calls Congresswoman Delgado to discuss a dinosaur protection group.
The name "Delgado" is a nod to animator and artist Ricardo Delgado, who played an integral role in the concept and storyboard art for Jurassic Park III. Delgado shaped the vision of the Spinosaurus for the film, but did not receive official credit. This small wink is a way of thanking the artist.
In the grand scheme of things, Jurassic World: Fallen Kingdom's director, J. A. Bayona, is relatively unknown to the general public. He had only directed three feature films before Fallen Kingdom, beginning with the critically acclaimed horror film The Orphanage, which kick-started Bayona's career.
Throughout Fallen Kingdom, the code "7337" is used to access the elevator and a few other secure areas. That number isn't random. It refers to the short film, 7337, directed by Sergio G. Sánchez. Bayona met Sánchez after seeing 7337, and Sánchez decided to give Bayona the script that would become The Orphanage.
One small but hilarious cameo from Jurassic World features the real-life Jimmy Buffet attempting to escape the dinosaur invasion while carrying two margaritas. Die-hard Buffet fans probably get a kick out of this, as the musician owns a chain of Margaritaville restaurants, a reference to his hit song.
Of course, the island (and presumably Buffet) are ultimately overrun by the dinosaurs. When the team returns to the island three years later in Fallen Kingdom, there's a visibly damaged Margaritaville sign lying in the rubble. Rest in peace, Jimmy.
Early in Fallen Kingdom, a news broadcast debates the merits of saving the dinosaurs from Isla Nublar. The volcano is erupting, and if nothing is done soon, the dinosaurs will all die. Some believe they should be saved, but others believe the dinosaurs should be allowed to go extinct once again.
Either way, upon close inspection, the news ticker displays the information that the "US president questions 'the existence of dinosaurs in the first place.'" It's a ridiculous statement in a world that's had dinosaurs for literally decades, and can only be meant as a dig towards President Donald Trump and his penchant for labeling everything as "fake news."
