This is a list of characters of the Stuart Little franchise that appear in the novel, films and other related media.

The Little family

Stuart Little

Stuart Little is the titular main character. He is a young white anthropomorphic mouse. He is a member of the Little family living in Manhattan in 1945 in the book, and later in 1999 to 2006 in film and television series. Although Stuart's age is never stated he has the mind and personality of a teenager. Critics have compared Stuart's life as a mouse entering a human world to that of an adolescent toward adulthood; which means that he is probably in his late teens or early 20s. Others see Stuart as giving children an empowering model of a small hero in a big world.

The novel presents Stuart as being born to human parents which some found problematic. The first film has Stuart adopted from an orphanage after the accidental death of his birth parents.Common Sense Media, "Little". Accessed December 16, 2014.name=Neuron>Sagoff, Mark.

George Little George Little (portrayed by Jonathan Lipnicki in the first two films, and voiced by Myles Jeffrey in the animated series and by Corey Padnos in Stuart Little 3: Call of the Wild) is the eldest son of the Little family and Stuart's adoptive older brother. George enjoys making friends with Mr. and Mrs. Little. His interests include toy models, racing model boats, and video games.

In the first film, George was excited at first about having a little brother until he found that his parents had adopted a mouse. He ignored Stuart until they played together with some of George's models, after which George became appreciative and defensive of Stuart. He fights a bully named Anton for insulting Stuart and initiates a search party when the police are unable to bring Stuart home.

George plays a slightly larger role in the second film, as Stuart convinces him to concoct a series of elaborate lies to cover for him, while he and Snowbell search for Margalo. Eleanor and Frederick eventually realize that George has lied to them. After being reprimanded for his deception and interrogated on Stuart's true whereabouts, George finally confesses where Stuart was last seen, prompting them to head out and look for him. His parents ultimately forgive both George for lying to them and Stuart for running away.

In Stuart Little 3: Call of the Wild, George is seen playing a handheld video game and develops a crush on Brooke, a Lake Scout at Lake Garland. George joins the Scouts to be close to Brooke.

Mr. Little

Mr. Frederick C. Little (portrayed and voiced by Hugh Laurie) is the patriarch of the Little family, and Mrs. Little's husband.

In the 1945 novel, his middle initial was revealed to be "C". It is unknown what C. stands for, and his middle initial was never used in any of the Stuart Little films or in the animated series.

He works at the New York Museum of Natural History and plays piano.

Mr. Little is supportive of his family, encouraging Stuart to see the bright side of bad situations and telling him the importance of perseverance. He tries to get his wife to let Stuart do physical activities despite her fears for his safety. In Stuart Little 3: Call of the Wild, when Mrs. Little refuses to let Stuart enroll in the Scouts due to his small stature, Mr. Little chips in saying it might do him some good, he was a Scout himself, and that he will watch out for him. Mr. Little volunteers himself to be in the Scouts as an assistant to Troopmaster Bickle. He also helps his wife remodel their cabin.

Mrs. Little Mrs. Eleanor Little (portrayed and voiced by Geena Davis in the films, and by Jennifer Hale in the animated series) is the matriarch of the Little family, and Mr. Little's wife.

In the 1945 novel, she was referred to as Mrs. Frederick C. Little. Her name was revealed in the 1999 film, as it was never mentioned in the 1945 novel.

She is a loving, kindhearted mother and can sometimes be overprotective of Stuart. Mrs. Little gave birth to Martha sometime after the events of the first film, and the DVD commentary for Stuart Little 2 reveals that she is a music teacher at Stuart and George's school. She demonstrates DIY skills in Stuart Little 3: Call of the Wild when she makes improvements to the family's lakeside cabin.

Snowbell

Snowbell is the family's Persian cat, Stuart's best friend and a former member of Smokey's alley cat gang. Snowbell is selfish, cowardly, and shallow, but lovable. He has been in the family longer than Stuart. George, Mr., and Mrs. Little are all oblivious to the fact that he can talk while Stuart is aware that he can talk.

In the first film, Snowbell is jealous of Stuart and plots to get rid of him. He considers eating him, but cannot as Stuart is a member of the family. Mrs. Little tells Snowbell that if he is ever caught eating Stuart, he is going outside permanently and can never again come back into the house. He tries to keep Stuart's existence secret from the alley cats because they will try to eat him and because their "mouse with a pet cat" relationship is an embarrassment. When the alley cats discover and hunt Stuart, Snowbell has a change of heart and defends him. Stuart returns the favor and they become friends.

In Stuart Little 2, Snowbell reluctantly helps Stuart look for Margalo, whom he has taken a dislike to, when she mysteriously disappears. Later, with the help of Monty, Snowbell finds Margalo from the Falcon, upset and very emotional at her departure.

Snowbell has further adventures camping with his family in Stuart Little 3: Call of the Wild, until he is eventually kidnapped by a mysterious beast, who only refuses to eat him when Snowbell suggested that she can fatten him up first in order to make a rug out of Snowbell's fur for the winter. However, Snowbell is eventually rescued, found by a search party, and happily reunites with Stuart to go home.

In the live action films, Lucky Prince serves as the primary physical actor for Snowbell.https://cinemacats.com/stuart-little-1999/ While in the sequel, other cats such Lucky, Tuffy and Rocky were used for additional and close-up shots.https://www.americanhumane.org/production/stuart-little-2/

Martha Little Martha Little (portrayed by Anna and Ashley Hoelck in the second film and voiced by Jennifer Hale in the animated series) is the infant daughter of the Little family who is Stuart and George's younger sister. Her character was created specifically for the film series. She is very messy and curious about the world.

In Stuart Little 2, Martha says her first words. In the animated series, Martha speaks more, but still sometimes gibbers. In Stuart Little 3: Call of the Wild, her only speaking is babbles and a single line.

Introduced in the 1945 book

Doctor Carey Doctor Paul Carey is a New York dentist. He is a kind individual who loves his patients, and a friend of Stuart's. His hobby is boat racing, and is the owner of the schooner Wasp, that Stuart thought "seemed to him finer and prouder than any other". He gave Stuart a tiny car when Stuart told him that he was travelling on foot to find Margalo.

Harriet Ames Harriet Ames is a girl of about Stuart's height and age. She is said to be one of the best-dressed girls in New York City, with clothes that are especially tailored just for her. Harriet is also said to come from a rich family. Stuart invites Harriet to go on a date with him in a miniature canoe, but discovers that it has been played with by the local children when they arrive.

LeRoy LeRoy is a fat, lazy 12-year-old boy who is the owner of the Lillian B. Womwrath, a model sailboat which always managed to beat the other competitors in the Central Park boat race. He convinced Stuart to man his boat for him in exchange for a peanut butter and jelly sandwich and his own radio, but Stuart turned down the offer. Stuart managed to beat his boat in the race by losing it in a thunderstorm.

Margalo Margalo (voiced by Melanie Griffith in the second film and Rachael Harris in the animated series) is a young anthropomorphic domestic canary, one of Stuart's closest friends and his love interest. She is kind and free-spirited and always there for the people she loves. In the 1945 novel, Mrs. Little adopted Margalo. Stuart becomes more infatuated with her the longer she stays. She saves Stuart's life when he stumbles onto a garbage barge, and is warned of Snowbell's plot to eat her and flies away from the Littles'.

In Stuart Little 2, Margalo was taken in by the Falcon, who raised her to steal Mrs. Little's two karat ring. Margalo befriends Stuart, leaves Falcon and gives Mrs. Little's ring back.

In the animated series, Margalo is a recurring character who sometimes visits the Littles.

Miss Gunderson Miss Gunderson was a character in the original Stuart Little novel who was mentioned, but never seen. She was the teacher at the local schoolhouse who was unable to teach her students due to being ill.

A similar teacher character makes a brief appearance in Stuart Little 2, portrayed by actress Maria Bamford. However, this character is unnamed, and has Stuart and George in her class, unlike the book counterpart.

Angora Cat The Angora Cat is an unnamed female Turkish angora cat who lives in a tool shed in a small park near the Littles' house after escaping from a cage in a pet shop. Snowbell formulated a plan with the Angora Cat that would allow Snowbell to eat Margalo.

Edward Clydesdale Edward Clydesdale is one of Dr. Paul Carey's patients who suggested where Stuart should look for Margalo. Most of his dialogue is barely understandable due to his teeth still being worked on as he was talking to Stuart.

Doctor Beechwood Doctor Beechwood (portrayed by Dabney Coleman) is a medical doctor who came to the Littles' house to take Stuart's temperature after Mrs. Little accidentally left him in the washing machine.

Beechwood had a small role in the 1999 film just like he did in the novel.

Introduced in the 1999 film

Monty Monty (voiced by Steve Zahn in the first two films, André Sogliuzzo in the animated series and Rino Romano in Stuart Little 3: Call of the Wild) is a gray tabby cat, Snowbell's best friend and a former member of Smokey's alley cat gang. He is an original character introduced for the film series. Monty is shown to be dimwitted, unintelligent and somewhat of a blabbermouth, earning him the nickname, "Monty the Mouth". Being an alley cat, he has vast knowledge of the various streets and alleyways of Manhattan. His personal goal throughout the series is to satisfy his appetite, which involves him attempting to eat Stuart or digging for scraps in the city. His catchphrase is "Pleeeeease?", which is commonly used when he is begging for food or something he personally desires.

In Stuart Little 2, Monty was physically portrayed by Merlin and Magoo.https://www.americanhumane.org/production/stuart-little-2/ According to the DVD commentary for the first film, Rob Minkoff was able to achieve most of the animals' movements with the help of editor Tom Finan. The shot of Monty laughing was achieved by the cat trainer giving the cat something to eat, as Minkoff had noted the cat would bob its head just the right way when eating.https://cinemacats.com/stuart-little-1999/
