Jurassic Park (1993)

Dinosaur blood extracted from a fossilized mosquito in Jurassic Park allows scientists to recreate dinosaurs with DNA. Based on this DNA, Dr Hammond genetically develops dinosaurs and opens a kind of zoo.
The first test visitors of this special zoo, where a variety of dinosaurs can be seen alive, are a lawyer, a mathematician, a dinosaur expert, a botanist, and the descendants of Hammond. When someone trying to capture the dinosaur embryos disables the security system, all the dinosaurs are set free on the island.
