In 1982, a team of highly talented animators blessed the world with the movie, The Secret of NIMH.
The fantasy cartoon classic was adapted from Robert C. O'Brien's 1971 children's book, which follows a field mouse attempting to save her home from destruction. With the help of recently freed laboratory rats, the plot ends in a truly feel good manner.
While most of us may assume we know everything about the gritty animated film, here are eight facts that'll make even the biggest fans say "rats!"
1. The film was animated by frustrated, former Disney employees
In 1979, several Disney workers left the famous animating studio, including animators Don Bluth, John Pomery, and Gary Goldman.
Dubbed "The Disney Defectors" by the media, the crew were in the middle of producing The Fox & The Hound, but could no longer stand their employer. This included Disney's bureaucracy and assembly-line attitude, along with its alleged neglect of certain animated skills and techniques.
2. There were significant differences between the movie and the book
Despite the 11 year gap between the movie and the book, it was startling to find out there are significant changes between the two mediums.
For instance, in the film, Mrs. Brisby's magical amulet wasn't included in the book (producers said it would have been difficult to showcase its symbolism on screen), Nicodemus was transformed into a rat from a wizard, Jenner became a main antagonist (instead of just being a mere traitor), and Mrs. Brisby's children are saved by their mother, as opposed to the heroic rats.
3. A toy company forced production to change a main character's name
Originally named Mrs. Frisby in the book, the production company was forced to slightly alter her name to Mrs. Brisby.
This was in order to avoid a potential trademark issue with the Wham-O company, otherwise known as the makers of the Frisbee.
4. John Carradine voiced his character high on painkillers
Carradine, who voiced The Great Owl, showed up to read his lines late and seemingly intoxicated. His agent told Goldman that his client suffered from a severe case of arthritis, and took medication to treat his diagnosis. He also mentioned Carradine may have had a martini at lunch.
Interesting enough, he was able to record all his lines in a single day.
