Summary
- Two original Jurassic Park books ignited a successful movie franchise with numerous adaptations.
- Missing book characters, like Bobby Carter and Ed Regis, didn't make it to the big screen.
- Dinosaurs like Clarence the Velociraptor and Ralph the Triceratops had unique personalities in the books.
The Jurassic Park movies and TV shows.
These two books launched a massive franchise, including six movies and the Jurassic World 4, which was truly impressive given the small amount of source material. Interestingly, because of the success of the films, Michael Crichton republished the two books in 1997, entitled Michael Crichton's Jurassic World. However, this had nothing to do with the Jurassic World trilogy of movies and was simply coincidental. Crichton introduced many to a fictional world where dinosaurs were brought back from extinction, and the humans who caused it, but some key book characters were missing from the Jurassic Park movies.

8 Bobby Carter
Investigative Care Giver
Roberta “Bobby” Carter appeared as a first aid assistant at the beginning of the Jurassic Park novel. Bobby had studied for two years at a medical institute in Chicago but left to work at a small hospital in the rural village of Bahía Anasco in Costa Rica, which was how she developed her skills. Bobby’s first interaction with anything dinosaur-related was when Ed Regis brought a young boy to her care, who sadly died from wounds caused by a Velociraptor.
This experience stuck with Bobby, and she dwelled on the outcome for quite a while.
Unfortunately, Bobby couldn’t understand the boy’s final words of “lo so raptor,” and not long after she photographed his wounds, she realized that her camera had been stolen. This experience stuck with Bobby, and she dwelled on the outcome for quite a while. Although Bobby didn’t appear in the Jurassic Park movies, there was a minor character with the first name of Carter (Thomas Rosales Jr.) in The Lost World: Jurassic Park.
7 Ed Regis
InGen's PR Manager
Ed Regis was a Public Relations Manager for Ingen, who didn’t survive the first book. Ed was described as having red hair and being a bit of a pushover after being forced into being a tour guide for the first expedition around the park and babysitting Lex and Tim. He was also frightened easily, and after the power cut out during the events of Jurassic Park, he wet himself, left the children alone in the car with the door open, and hid in a pile of rocks while Rexy unleashed terror around them.
Nevertheless, Ed Regis would have also dampened the seriousness of the situation and the tense atmosphere overall.
Having Ed Regis in the Jurassic Park movie would have made one of Steven Spielberg’s best action scenes very funny, especially if he’d replicated his actions from the book. Nevertheless, Ed Regis would have also dampened the seriousness of the situation and the tense atmosphere overall. Unfortunately, Ed Regis met a bitter end after a baby Tyrannosaurus Rex ate him, and all that was left of his body was a single leg.
6 Bob Morris
A Tongue Tied Researcher
In the Jurassic Park book, Bob Morris was a lawyer for the San Francisco division of the Environmental Protection Agency. His role primarily involved investigating the technology embedded in Isla Nublar, which he found odd because it was so powerful, yet was moved to an isolated island. Bob also found it unusual that the Hammond Foundation was funding Dr. Alan Grant’s digs while also hoarding large quantities of amber for a reason he didn’t understand.
The book contained a vital interaction between Bob Morris and Alan Grant that would have been useful in the movie.
The book contained a vital interaction between Bob Morris and Alan Grant that would have been useful in the movie. Bob struggled to convey his fears about InGen and the Hammond Foundation, which made Grant brush his vague concerns off, believing it wasn’t his business. If this moment between the pair had been included in the film, it would have been a great piece of foreshadowing and provided audiences with more context on the villainous company that ran the park.
5 Manuel Aragón
Bobby Carter's Paranoid Assistant
Manuel Aragón was Bobby Carter’s assistant and assisted her with the child wounded by a T-Rex. Manuel was a native of Costa Rica and was highly superstitious, which only grew throughout the events of Jurassic Park. After an injured worker mentioned that he was attacked by a “raptor,” Manuel became ridiculously fearful of everything around him and refused to work anymore. According to him, “raptor” really meant “hupia,” a term used in the Taino culture to refer to the spirit of a dead person.
However, Manuel didn’t realize that the worker was being literal and talking about the actual dinosaur.
However, Manuel didn’t realize that the worker was being literal and talking about the actual dinosaur. Although he was entitled to his beliefs, Manuel’s selfish actions caused the death of the injured worker. As Bobby tried to resuscitate him, Manuel stood by and declined to help her, worried that the “hupia” would consume him. Although Manuel would have been a great addition to the Jurassic Park movie, his attitude wouldn’t have been a great fit if he wanted to survive.
4 Ellen And Mike Bowman
A Pair Of Distracted Parents
Ellen and Mike Bowman, a married couple vacationing with their daughter Tina, appeared in the first Jurassic Park novel. Although they were simple civilians, they had some interesting subplots. For example, Ellen was overly critical of her daughter and constantly commented about her weight despite Mike’s disagreement. Ellen also had an irrational fear of snakes, so she refused to let Tina out of her sight. However, her opinions were quickly forgotten about when a Procompsognathus bit Tina.
Luckily, Tina was completely fine, no thanks to her parents being constantly distracted by trivial things.
Luckily, Tina was completely fine, no thanks to her parents being constantly distracted by trivial things. Unbeknownst to Mike, Ellen had planned their trip to Costa Rica as a front for her visiting a plastic surgeon, and although they argued and made up, there was no doubt that the lingering effects of their drama stopped them from keeping an eye on their daughter. Even though the Bowmans weren’t in the Jurassic Park movie, there was another Bowman family in The Lost World: Jurassic Park, but they had minimal screen time that didn’t cover much of the story from the book.
3 Tina Bowman
A Future Palentologist
Tina Bowman alone was a fascinating character and stood apart from her parents. Despite her mother’s fears, Tina was keen to explore the beach where they were relaxing because she wanted to search for exotic animals for a school project. Tina’s interest in science was a prominent feature of her character, and she was more than happy to talk about the Procompsognathus that injured her to Dr. Marty Gutierrez after recovering.
The only common factors between the two Bowan families were that they shared a surname and Tina’s film counterpart, Cathy (Camilla Belle), was bitten by a creature.
The doctors around Tina noted her exceptional observation skills for a few reasons, such as how easily she could draw an image of the lizard-like creature from memory and how Dr. Crux wore a different shirt every day but always the same tie. The only common factors between the two Bowan families were that they shared a surname and Tina’s film counterpart, Cathy (Camilla Belle), was bitten by a creature. The books made the Bowans characters worth investing in, and they would have been an exciting addition to the movies if they had an appropriate amount of screen time.

Jurassic Park: Biggest Differences Between The Book & Spielberg’s Movie
Jurassic Park differs significantly from Michael Crichton's novel, including which characters live and die, and some major parts of the story.
2 Dr. Marty Gutierrez
An Important Character Missing From The Jurassic Park Movies
Dr. Martin Gutierrez, also known as “Marty,” was one of the few Jurassic Park characters to appear in both novels. Marty was an American field biologist at the Carare National Park in Costa Rica and first appeared in the book after Tina Bowman was attacked. Marty then set off to the beach where the incident happened, and after some searching, he was shocked to find the same lizard that injured Tina being eaten by a monkey. After the events of Jurassic Park, Marty told the falsely incarcerated Alan Grant about his discovery, which brought the first book to a close.
Despite being a minor character, several little details littered throughout the books about Marty rounded him out as a character, such as his love for wearing tweed and khaki and his distinct beard.
Marty was less prominent in The Lost World but continued to track a pattern of animal corpses that washed up on the beaches of Costa Rica, theorizing that the creature he’d seen was behind it. Despite being a minor character, several little details littered throughout the books about Marty rounded him out as a character, such as his love for wearing tweed and khaki and his distinct beard. Unfortunately, Marty wasn’t featured in the Jurassic Park movies. However, there was a possible nod to him in the character of Sammy Gutierrez from the TV show Jurassic World: Camp Cretaceous.
1 Clarence The Velociraptor And Ralph The Triceratops
There Were Other Dinosaurs With Names And Personalities The Films Didn't Include
Several dinosaurs stood out throughout the Jurassic Park films for having distinct personalities and even names. For example, in the first film, the T-Rex that caused terror and destruction all across the park was called Rexy, and Jurassic World introduced Owen Grady’s (Chris Pratt) favorite Velociraptor, Blue. However, a few dinosaurs received a special mention in the books but didn’t appear in the films.
Including these dinosaurs would have been an exciting opportunity for Jurassic Park to expand on its character development for both the humans and the dinosaurs.
Clarence, a green Velociraptor that Alan Grant tranquilized during a breeding session, lived underneath the park with a wild population of other dinosaurs, for example. There was also Ralph, a female Triceratops spotted by Lex eating grass outside Grant’s makeshift hideout. Lex took a particular liking to Ralph and gave the dinosaur the name, but only because it reminded her of a child she went to school with. Including these dinosaurs would have been an exciting opportunity for Jurassic Park to expand on its character development for both the humans and the dinosaurs.
