Jurassic Park: 8 Unbelievable Differences Between The Book And The Film

It is no secret that Dr Grant is a bit of a grumpy, quiet character in the movie. He's a good guy, don't get me wrong, but he's hardly a people person. He has no interest in Timmy, no care for the boy's passion for dinosaurs, and doesn't think much of anything besides fossils and Dr. Sattler.

This, however, is quite far from Dr. Grant in the book. Dinosaurs and their nature are still his primary concern, of course, but he is more patient and nurturing towards the kids. He takes an interest in Timmy, instigating conversation himself about their mutual fascination of dinosaurs, and adopts the fatherly role without much resistance. This may have to do with the fact that Lex is much younger in the book than in the film, but overall Grant is much more affectionate to his companions.

The character in the film takes to this role over time, but he is far less willing to change. He avoids Timmy when the tour is due to begin, dislikes Lex holding his hand when they discover the ill Triceratops, and is just generally disinterested in the social aspects of the trip. His literary counterpart is, all in all, just a nicer guy.
