Jurassic Park IVSome quotes from other sites:
"We're told that the film is about the government who has trained dinosaurs to carry weapons and use them for battle purposes."
"Nick is put in charge of training these five dinosaurs, X1 through X5, and the first thing he does is name them. “Any soldier worth his pay has a name to answer to, not a number,” he says. So we are introduced to Achilles, Hector, Perseus, Orestes, and Spartacus, each of them a specially created deinonychus, which is sort of like a miniature T-rex. They have super-sensitive smell and hearing, incredible strength and speed and pack-hunting instincts, and they have modified forelegs, lengthened and topped with more dextrous fingers, as well as dog DNA for increased obedience and human DNA so they can solve problems well. All of this is topped off with a drug-regulating implant that can dose them with adrenaline or serotonin as the situation demands."
