Hilfe, ich hab meine Lehrerin geschrumpft

Who will ever believe 11-year-old Felix Vorndran (Oskar Keymer) that he has shrunk the school principal Dr. Schmitt-Gössenwein (Anja Kling), who is hated by everyone, to the height of 15 centimeters? He doesn't know himself how this happened and whether it might have something to do with the spirit of the school's founder, Otto Leonhard (Otto Waalkes)? But he now has the problem on his neck, more precisely in his backpack. Because there she is now, the little director, and is still complaining. Together with his girlfriend Ella (Lina Hüesker) and against the resistance of his rival Mario (Georg Sulzer) and his father, school administrator Henning (Justus von Dohnányi), he has to try everything to get her back to her normal size. If only she wouldn't be so annoying...

The leading roles in 'Hilfe, ich hab meine Lehrerin geschrumpft' (2015) are played by Anja Kling (from 'Hanni & Nanni') as school principal Dr. Schmitt-Gössenwein, Justus von Dohnányi ('Männerherzen') as school administrator Henning and Axel Stein ('Nicht mein Tag') as Peter Vorndran. Otto Waalkes appears as a guest star. The children's roles have been taken over by Oskar Keymer as Felix, Lina Hüesker as Ella and Georg Sulzer as Mario. The screenplay for this turbulent comedy was written by Gerrit Hermans. Comedy specialist Sven Unterwaldt, who has already proven with '7 Dwarfs' and 'Otto's Eleven' that he can stage the best family entertainment, directed the film. The film adaptation of the children's book bestseller of the same name by Sabine Ludwig is a German-Austrian co-production.
