Michael Crichton's Jurassic Park offers a stark warning about scientists' God complex and the uses of genetic science research in the production of entertainment for the masses. Both book and film see John Hammond, founder of International Genetic Technologies (InGen), invite respected members of the scientific community to inspect his new theme park and research facilities based on a remote island. He has brought dinosaurs back from extinction and wants to use them as the centerpiece of his attraction. Following industrial sabotage, the island is on lockdown, and security fences separating man from beast are deactivated: the dinosaurs are on the loose and start to kill. Steven Spielberg's adaptation used the latest computer-generated imagery (CGI), special effects, and animatronics to recreate those iconic creatures for the big screen, influencing Hollywood film production even into the late 2010s.
