Flawed film premises weren’t invented in the last decade.
In 1977, a gentleman named Lorenzo Music was developing an animated feature called Simon and Miranda, which starred a snail named Simon and his love interest, Miranda the caterpillar. Music had successfully developed and produced snail-free TV shows like The Bob Newhart Show and Rhoda, and needed advice if his latest idea was worthwhile.
For guidance, Music reached out to Ward Kimball, who had spent nearly forty years as a director, writer and animator at Disney, and had excellent instincts about entertainment. Kimball, of course, was also responsible for creating the most successful insect in animation history—Pinocchio’s Jiminy Cricket—and though snails aren’t technically insects, for Music’s purposes, they were close enough.
