The Adventures of Prince Achmed (known as Die Abenteuer des Prinzen Achmed in German) is a 1926 German animated fairytale film by Lotte Reiniger. It is the oldest surviving animated feature film; two earlier ones were made in Argentina by Quirino Cristiani, but they are considered lost. The Adventures of Prince Achmed features a silhouette animation technique Reiniger had invented which involved manipulated cutouts made from cardboard and thin sheets of lead under a camera. The technique she used for the camera is similar to Wayang shadow puppets, though hers were animated frame by frame, not manipulated in live action. The original prints featured color tinting. Several famous avant-garde animators worked on this film with Lotte Reiniger, among them Walter Ruttmann, Berthold Bartosch, and Carl Koch. The story is based on elements from the One Thousand and One Nights written by Hanna Diyab, including "Aladdin" and "The Story of Prince Ahmed and the Fairy Perī-Bānū". Plot An African sorcerer conjures up a flying horse, which he shows to the Caliph. When the sorcerer refuses to sell it for any amount of gold, the Caliph offers any treasure he has. The sorcerer chooses Dinarsade, the Caliph's daughter, to her great distress. Prince Achmed, Dinarsade's brother, objects, but the sorcerer persuades him to try out the horse. It carries the prince away, higher and higher into the sky, as he doesn't know how to control it. The Caliph has the sorcerer imprisoned. When Achmed discovers how to make the horse descend, he finds himself in a strange foreign land, a magical island called Wak Wak. He is greeted by a bevy of attractive maidens. When they begin fighting for his attention, he flies away to a lake. There, he watches as Pari Banu, the beautiful ruler of the land of Wak Wak, arrives with her attendants to bathe. When they spot him, they all fly away, except for Pari Banu, for Achmed has her magical flying feather costume. She flees on foot, but he captures her. He gains her trust when he returns her feathers. They fall in love. She warns him, however, that the demons of Wak Wak will try to kill him. The sorcerer frees himself from his chains. Transforming himself into a bat, he seeks out Achmed. The prince chases the sorcerer (back in human form) and falls into a pit. While Achmed fights a giant snake, the sorcerer
