I discovered this online recently and thought you really ought to see it. It’s from a 2005 Canadian documentary about the “legendary sin cities” of the 1920s and 1930s including, naturally, Berlin. Its depiction of Weimar licentiousness is familiar Strange Flowers terrain, but there’s some great footage and thoughtful talking heads.
Anita Berber is there, naturally. Berber biographer Mel Gordon, recently mentioned in these pages, talks about the woman who shocked even the blasé Berliners. Also analysing this unprecedented period of social experimentation is David Clay Large, author of Berlin: A Modern History.
