The Masrani website included information that was absent from the film; it contained details of the company's purchase of InGen and about the park's origins. The Masrani website also included videos showing D'Onofrio and Wong talking in-character about the fictional company. Paleontologist Brian Switek was hired in early 2015 to ensure the accuracy of dinosaur information on the film's theme park website. Trevorrow wrote fictional customer comments for the theme park website; he said, "It was then that I realized I'd gone too far down the rabbit hole". Closed circuit video shown on the control room monitors was filmed during production and was also added to the theme park website.
