In 1923, at the start of their collaboration on what would become The Adventures of Prince Achmed, Walter Ruttmann asked Lotte Reiniger, the film’s creator, director and chief animator, why she was making a fairy tale – what did it have to do with the year 1923? ‘Nothing at all,’ she told him. ‘And why should it? I’m here, living in the year 1923, and I have the chance to make this film, so naturally I’m going to do it. That’s all it has to do with the year 1923.’
