[ThomasG on Berthold Bartosch]: In 1932, Masereel's publisher Kurt Wolff commissioned Czechoslovakian animator Berthold Bartosch to create an animated version of The Idea. Bartosch came to the project with sterling credentials, having collaborated with animator Lotte Reiniger on the world's oldest surviving animated feature film The Adventures of Prince Achmed in 1926. It was Bartosch who created most of the brilliant atmospheric effects on Achmed, and he outdid himself on The Idea.
