The 1930 German tragicomedic film “The Blue Angel”, based on author Heinrich Mann’s 1905 novel “Professor Unrat” (“Professor Garbage” in English), is considered to be the first major German sound film. However, the film was shot simultaneously in German- and English-language versions. The latter version was considered a lost film for many years. The German version is much better known because of this. Still, a print of the English-language version was discovered in a German film archive and restored. On January 19th, 2009 the restored English version had its U.S. premiere at the Castro Theatre in San Francisco as part of the “Berlin and Beyond” film festival.
On a final note, for a time, “The Blue Angel” was banned in Nazi Germany in 1933, as were all the works of author Heinrich Mann and playwright Carl Zuckmayer.
So whether it was losing a print or the horrible ban of books based on the worst of times of a nation, “The Blue Angel” survived and years later lived on for generations to see, showing that the worst of man cannot stop the beauty of art.
