The Adventures of Prince Achmed - German: Die Abenteuer des Prinzen Achmed - 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.
