Crichton noted that because the book was "fairly long" his script had about 10 to 20 percent of the novel's content; scenes were dropped for budgetary and practical reasons, and the violence was toned down.
Crichton megjegyezte, mivel a könyv „meglehetősen hosszú”, a szkriptje csupán annak 10-20%-át tartalmazza; számos jelenet költségvetési és gyakorlati okokból maradt ki.
