A light-hearted look at German Jews, Alles auf Zucker! (Go For Zucker!), has won best picture, director and actor in Germany's equivalent of the Oscars.
Dani Levy (C) , Henry Huebchen (L) and Hannelore Elsner: All up for prizes
It was nominated in 10 of 15 categories at the German Film Awards.
The movie, directed by Swiss Dani Levy, sees a hard-up Jewish man (Henry Huebchen) try to convince his Orthodox brother that he is actually kosher.
It was produced in just 23 days as a TV film but outshone Oscar nominee The Downfall, which had three nominations.
Bruno Ganz was nominated for best actor in Der Untergang (The Downfall)
It has been praised by film critics and Jewish leaders alike for taking an everyday look at life in a country where films on Jewish themes have tended to focus on the Holocaust.
The film - which won the Ernst Lubitsch award for best German comedy earlier this year - has also been sold to more than 10 countries.
Other nominees for best picture were Agnes und seine Brueder (Agnes and his Brothers), Der neunte Tag (The Ninth Day), Der Wald vor lauter Baeumen (The Forest for the Trees), Die fetten Jahre sind vorbei (The Educators) and Sophie Scholl - Die letzten Tage (Sophie Scholl - The Final Days).
Nominations for Der Untergang (The Downfall), which prompted controversy with its attempts to humanise Hitler, included two for best supporting actress and a best actor nomination for Bruno Ganz.
Last year's German Film Awards were dominated by romantic drama Gegen die Wand (Head On), which won five prizes including best film.
