Like many artists of his time, Walter Ruttmann discovered film as a medium of experimentation with revolutionary forms of expression. He gave up easel painting in 1918 and acquired the first German patent for an animation stand in 1920, thus creating the technical prerequisites for his “Opus” series: abstract elements of painterly gestures and cardboard moved by stop-motion.

A huge, cheeky rat has moved in with the little man. It whistles to the music from the radio, helps itself from the fridge without asking, splashes in the bathtub and is simply everywhere – loud, annoying, just too much. When it suddenly disappears, the little man realises that the apartment has never been so quiet – and so empty. A heart-warming adaptation of Nadia Budde’s eponymous picture book.
