Before watching the movie:
This is a story that gets remade every so often, probably because the state of film technology marches on and someone decides they can do better than the last one. Certainly, the recent version with Jack Black established the look very realistically. However, hardly anyone has adapted the entire book, and the title is almost universally considered to refer to only the Lilliput section, which this appears to do. Brobdingnang sometimes gets included since it’s just the reverse of the scale effect, but to my knowledge no version, or at least no enduring version, has attempted, for example, the island of the horse people. Not even the Harryhousen-powered The Three Worlds of Gulliver tried.
This is a staging by another great name in animation and effects, Fleischer Studios. I feel animation is underrepresented on this site, and I’m glad to bring in a historically significant animated feature now. I’ve never really cared much for the Fleischer style, so much as I’ve seen it, but Fleischer didn’t really endure long enough to develop as well as Disney and Warner Bros. did. But it should serve to tell the story adequately.
