Two fantasy novels by Margery Sharp were combined for in the Disney animated feature The Rescuers. The title characters are a pair of mice, Bernard and Miss Bianca. A little girl named Penny has been kidnapped by Miss Medusa.
When the human law enforcement officials fail to locate the child, Bernard and Miss Bianca take over with the help of several colorful animal companions. In classic Disney tradition, the comedy element is offset by moments of genuine terror.
Voices are provided by Bob Newhart (Bernard), Eva Gabor (Miss Bianca), Geraldine Page (Madame Medusa), Jim Fibber McGee Jordan, John McIntire, George Goober Lindsay, Joe Flynn (who died in 1974, not long into the four-year production), and a host of others.
It scored at the box office, more than compensating for the $8 million investment and the half-decade of work it took to complete the film. In fact, The Rescuers remains one of the most popular of the Disney cartoon films produced after the death of Uncle Walt. A heavily-computerized sequel, The Rescuers Down Under, appeared in 1990.
