Nasrudin (partially found cancelled animated film and early prototype for "The Thief and The Cobbler"; early 1970s)
From The Lost Media Wiki
Still from surviving footage of the film.
Status: Lost
Nasrudin is an early title of the film that would become The Thief and the Cobbler, created by Richard Williams. The film would have been based off of a series of books about the tales of Mulla Nasrudin written by Idries Shah, which Williams illustrated.
By 1972, 3 hours of footage was completed, but Williams had a falling out with the Shah and abandoned the project. The Shah family gained the rights to Williams's illustrations, but the completed animation has never been released.
All that has resurfaced is just a short clip of the film from a documentary called One Pair of Eyes. The whereabouts of the original film are unknown, and little else about the film exists.
