Assembled in Hungarian by novice producer Robert Halmi and equally "green" director Bill Feigenbaum, Hugo the Hippo is an easygoing feature-length cartoon. Hugo, a baby hippopotamus living in ancient times, is persecuted by a world populated by hippo-haters. Foremost among these reprobates is Aban Khan, who in the English-language version of this film is voiced by Paul Lynde. Hugo perseveres with the little help of some new friends, both animal and human. Only fitfully successful in theatres, Hugo the Hippo later gained a huge following thanks to its ready availability in the early days of videocassettes.
