Origin Mrs. Brisby first appears in the 1982 film
The Secret of NIMH, directed by
Don Bluth, which is directly based on the
fantasy/
science fiction children's book Mrs. Frisby and the Rats of NIMH, which was written in 1971 by
Robert C. O'Brien and illustrated by Zena Bernstein. The book won the
Newbery Medal in 1972. The book's story follows a widowed field mouse named Mrs. Frisby, who cares for her four children in a farmer's garden. The farmer, Fitzgibbon, was planning on deploying his plow for his garden, meaning Mrs. Frisby had to move her family out of the garden. Because her son, according to the doctor mouse, Mr. Ages, was gravely ill and therefore could not survive having to travel out of his home, Mrs. Frisby must seek help from an old owl, and the bird informed her to seek out an intelligent rodent group called the "Rats of NIMH" (abbreviation of
National Institute of Mental Health) so that they could help to relocate Mrs. Frisby's house and thereby save Timothy and the other children. Don Bluth's independent animation career from
Walt Disney Animation Studios began in 1979 when he and his colleagues
Gary Goldman and
John Pomeroy began experimenting with a classical style of animation that they felt was lacking in Disney's studio. After independently producing the short film
Banjo the Woodpile Cat in his own
Don Bluth Productions, another film production company called
Aurora Productions contacted them, offering them a budget for a feature film. Bluth and sixteen other people left
Disney to produce the movie. Bluth, in his autobiography, praised the story told in
Mrs. Frisby and the Rats of NIMH, speculating that
Walt Disney would have adapted it into a movie if O'Brien contacted him while both were still alive.
Characterization and design Consistent with O'Brien's book, Don Bluth went on to make Mrs. Frisby the protagonist of his adaptation. In the film, Mrs. Brisby is a field mouse who has brown fur and dons a red cape. She is a widowed mother who cares for her four children and lives with a housekeeper named Auntie Shrew. Mrs. Brisby is kind and soft-spoken in personality, but in a mournful state due to the death of her husband which occurred before the film's events. Throughout the film, her forename and maiden name are never revealed. Mrs. Brisby's emotional strength was drawn from that of Bluth's grandmother. As many as 46 different color palettes of Mrs. Brisby were created so that she appeared in different levels of shading throughout the film. Mrs. Brisby was likely difficult to animate due to her delicate gestures consistent with her timid personality, which were in contrast to the more exaggerated movements of her friend, a comedic crow named Jeremy.
Voice and name change In his autobiography, Bluth wrote that he knew that the vocal performance role of Mrs. Brisby would be inherently challenging. He feared that a less capable voice actress would have a whiny tone while reading through the film's lines. Bluth recalled that Hartman "read the lines with an ever-so-slight tremble to her voice, turning Mrs. Brisby into a timid and unsure character," making the fictional mouse easier to sympathize with. He thought that Hartman was cleverly reading Brisby's lines but eventually realized that her voice acting reflected her depression in reality when he learned that the actress took her own life in 1987. Since the tragedy, the director wrote that he found it emotionally painful to rewatch
The Secret of NIMH. The production crew learned that they were unable to use the name "Frisby" due to trademark issues over
Mattel's
Frisbee throwing disc. Because the voice lines were already recorded, the crew were faced with the threat of having to re-record the lines at a detrimental financial cost. However, industrial sound designer, David Horten, used a razor blade to scrape the magnetic track, splicing the "F" sound in "Frisby" into a "B" sound for one scene. He then played the audio of the Great Owl stating, "Brisby ... Mrs.
Jonathan Brisby?" to the surprise of the crew. Later he spliced many "F"s into "B"s. == Appearances ==
