A Thousand and One Nights is a 1969 anime feature film directed by Eiichi Yamamoto, collaborating with Osamu Tezuka, and the first entry in Mushi Production's Animerama trilogy, a series of anime films aimed for adult audiences.
The film was given an American release at some point, complete with an English dub, predating the adult animated film fad that Ralph Bakshi's Fritz the Cat would later kick off. However, while the film was a hit in Japan, it flopped in the United States, where it only received a limited release.
To date, the English dub of A Thousand and One Nights has yet to resurface and is believed to be lost. The English dub trailer was on Youtube until recently, when it was taken down for copyright infringement.
