As we said in the article on Margarete von Trotta's "Hannah Arendt: in praise of thought", this is a producer who has never been afraid of tackling difficult subjects. The life of Rosa Luxemburg is one such: rendering into dramatic, cinematic form the life of a profound political thinker and one moreover whose personal, private life was rich and often painful, was never going to be easy. Of course, a film could never capture in its full complexity Luxemburg's theoretical contribution to the workers' movement. Nonetheless, in our view it does justice to the ethos of her life and to her courage and great-heartedness as a person. We encourage our readers to take the opportunity to watch the film with English sub-titles before the laws of copyright get it removed from the Internet.
