Fallen Kingdom lifts plot elements from the fallen screenplay even more blatantly. JP4 sees tough guy Nick Harris returning to the ruins of Jurassic Park in order to recover Nedry's DNA-filled Barbasol can for John Hammond -- who apparently doesn't realize the can only had "enough coolant inside for 36 hours." Hammond does, however, deduce that smelly old Newman couldn't possibly have used a deodorant can.
Possibly because watching an ex-soldier hunt for an I.T. guy's rotting corpse and a can of hopelessly warm embryos doesn't sound super fun, Nick is soon confronted by the park's security rangers, who appear "out of the trees all around him" -- kind of like the security guys who betray and attack Owen during his mission back to Isla Nublar.
