20 Things You Somehow Missed In Jurassic Park
19. Mr. DNA Was No More Than Clever Exposition
While receiving the tour of the facility, Dr. Grant, Dr. Sattler, and Ian Malcolm are given a video presentation about how the park was conceived by a very friendly animated strain of acid called Mr. DNA. While it's a bit of a hokey scene and incredibly heavy on the exposition, it was a request made by the filmmakers to try and control the budget.
By having one cheesy scene that explains the entire premise of the film, how they discovered the dinosaurs, and how they subsequently built the park, it saved millions of dollars on the writing and filming required to transmit that information to the audience otherwise. Not to mention keeping the runtime down.
