Errol Morris’s Fast, Cheap & Out of Control interweaves the stories of four men, each driven to create eccentric worlds from their unique obsessions, all of which involve animals. There’s a lion tamer who shares his theories on the mental processes of wild animals; a topiary gardener who has devoted a lifetime to shaping bears and giraffes out of hedges and trees; a man fascinated with hairless mole rats; and an MIT scientist who has designed complex, autonomous robots that can crawl like bugs.

驯兽师戴维•胡佛（Dave Hoover）、园艺师乔治•蒙德卡（George Mendonça）、鼹鼠专家雷•门兹（Raymond A. Mendez）、机器人发明家罗德尼•布洛克斯（Rodney Brooks），这四个看起来全不搭调的人被聚集在同一个影片中。他们畅谈自己的人生、工作以及点点滴滴的感悟，这四个似乎风马牛不相及的行业，隐约却又有着些许关联。
