Director Donnersmarck spent a month translating the screenplay into French and sending it to
Gabriel Yared to entice his participation as composer for the film. For the scene in which Dreyman plays the Sonata For A Good Man on piano, Donnersmarck asked Yared to write a composition that in two minutes would turn Lenin away from all the atrocities he later committed. This pivotal scene was the germinal idea around which the original screenplay was conceived and constructed.
