Any time a book is adapted into a feature film, there are bound to be some changes, and Jurassic Park is no exception to this rule, as there are a few missing deaths from the book. Steven Spielberg’s Oscar-winning 1993 adaptation of Jurassic Park has many key differences from Michael Crichton’s original novel, including the ending. Of course, both versions do follow the same general story; a group of characters must fight for their survival when a theme park featuring live dinosaurs begins to lose its hold on the reanimated creatures.
