"What if Dean Martin got shrunken down and put inside Jerry Lewis?" That was writer Jeffrey Boam's clever take on his rewrite of a straight spy-fi script conceived by producers who had seemingly never heard of Fantastic Voyage. It attracted director Joe Dante, looking to make a commercial hit after the failure of Explorers. But in the end, of course, it turned out to be just as wacky as his earlier stuff, and its most appreciative audience emerged a year later via home video. ILM won an Oscar for its still impressive pre-CGI special effects.
