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.
