Watu Wasio was a movie, presumably produced in 2552 or earlier. It ran for about two hours and fifteen minutes. Nothing is known of its storyline but the movie's promotional poster seems to suggest that it is a movie for younger children, and involves animals as the main characters, including a dog and some form of bird.
The Swahili word "watu" means "people." While "wasio" is not a word, "wa" means "they" applied to people or animals, and "sio" means "are not." Thus, the film's title can be translated as People They Are Not or They are not People.
