Why did the film adaptation of Mrs. Frisby and the Rats of NIMH into The Secret of NIMH rewrite the end plot with that stupid mystical jewel-locket-thing?
They pretty much rewrote the entire premise of the book. It was originally about lab rats who acquired human-level intelligence from experiments, and then had to rapidly build a civilization from scratch. Disnification turned it into some typical magical talking animal thing.
Disnification? Don Bluth wasn't at Disney at that point, so give credit where it's due. :)
Yeah, he rewrote the premise, and now it's about saving your family from imminent nuclear/tractor-related apocalypse with a lab-rat sideshow. Ironic, since this means Frisby is about the NIMH story while Secret of NIMH is about Mrs Frisby (/Brisby, per Frisbee Corp. lawsuit concerns).
