The universe that Michael Crichton and Steven Spielberg created with 1993’s Jurassic Park is a world ripe with all kinds of possibilities. What would a world in which the resurrection of extinct species is a reality be like? Can an ostensibly foolproof system of controlling these creatures and making sure they don’t escape their enclosures really work? (No.) Does life, uh, find a way? (Yes.) This summer’s Jurassic World chose to tell a simpler, more action-y tale than its predecessors, but from what Colin Trevorrow has said about its sequel, Jurassic World 2 will take a more nuanced approach to the possibilities of genetically resurrected dinosaurs.
