A lot or a little?

The parents' guide to what's in this movie.

Educational Value

Purely designed as entertainment, though kids might want to know more about animal testing after the movie.

Positive Messages

Includes themes of animal cruelty and animal experimentation, but also teamwork and freedom.

Positive Role Models & Representations

Mrs. Brisby is brave for her family, and several other characters are helpful and kind, even if they seem a little creepy. One villain is power hungry and plots a murder. Characters demonstrate teamwork, perseverance, and courage.

Violence & Scariness

Lots of creepy, dark imagery, only occasionally lightened with humor. A scary and dramatic sword fight between rats with a little blood that results in the death of one rat. Two bad rats plot to kill a main character and make it look like an accident; they are successful. Mrs. Brisby's children are in great peril and almost drown in the mud. Rats, as well as dogs, cats, and monkeys, are subjected to scientific experiments including a scene of an injection in a flashback. A big spider crawls toward Mrs. Brisby before it's crushed by a giant owl. Characters eyes glow and might appear scary to some.

Sexy Stuff

The crow talkes about "looking for a lady" and "making a love nest." Some flirtation between a male and female crow.


One "damn."

Drinking, Drugs & Smoking

The rats drug the cat on occasion to make it sleep.

What parents need to know

Parents need to know that this The Secret of NIMH about a group of intelligent rats who escape from an animal laboratory is suspenseful and rather dark. Several scenes include animal children in peril and a sword fight between rats ends in one death with a little blood. The worst part for sensitive viewers: a flashback shows the animated animals being imprisoned and injected with a needle.

What's the story?

In THE SECRET OF NIMH, Mrs. Brisby (Frisby in Robert C. O'Brien's prize-winning book, Mrs. Frisby and the Rats of N.I.M.H.) is a widowed mouse living on a farm with her four children, including Timmy, who's bedridden with pneumonia. When they're forced to find a new home, the Great Owl advises Mrs. Brisby to seek the help of Nicodemus, the king of the rat colony. Venturing underground, she discovers an entire civilization of rats that tell her that they revere her late husband Jonathan. Nicodemus explains that Jonathan helped them escape from NIMH -- the National Institute of Mental Health -- when he was a fellow prisoner there and where they were experimented on and injected with super-intelligence drugs. Nicodemus agrees to help Mrs. Brisby move Timmy and gives her a magic amulet. She returns to the farm to find that her home is sinking in the mud and hopes the amulet can really save them.

Is it any good?

Conceived as a return to the lush, "old-fashioned" style of such Disney classics as Pinocchio, this animated movie is an impressive example of cartoon art. It features fully animated character motion and a three-dimensional look. The animation is rich and warm, filled with exquisite detail and color, which brings the dazzling, set pieces to life (including a duel during a lightning storm, and the finale involving the magic amulet).

The voice cast is also excellent, boasting such names as the distinguished British actor Derek Jacobi, veteran character actor John Carradine, the reliably comedic Dom DeLuise, and even a young Shannen Doherty as a mouse. However, parents should be strongly cautioned that the story's tone frequently careens from cheerfulness to grimness, which may frighten children. The Secret of NIMH does not shy away from being downright terrifying at times, most notably during a gruesome flashback showing animals being tortured.
