The entire budget of the film, about 2 million dollars (1.6 million Euro), was possible only because the actors were willing to work for 20% of their customary salary.
All the listening/recording props used in the film are actual Stasi equipment on loan from museums and collectors. The props master had himself spent two years in a Stasi prison and insisted upon absolute authenticity down to the machine used at the end of the film to steam-open up to 600 letters per hour.
The punchline of the joke that Grubitz tells in the cafeteria, about there being no difference between Honecker and a telephone, is a play on the words 'aufhängen' and 'neuwählen'. In terms of a telephone it means hang up and redial, respectively. In terms of politics it means hang somebody and elect someone new.
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.
The film set a record in 2006 for getting the most nominations (11) for the German Film Awards ever.
In a book describing the background story of this movie, Ulrich Mühe accused his ex-wife Jenny Gröllmann of being an unofficial agent for the East German secret service ("Staatsicherheit").

According to Florian Henckel von Donnersmarck's commentary on the deleted scene of the prostitute at Wiesler's apartment, he auditioned real prostitutes for the part, until finally casting body painter Gabi Fleming.
Although it was very common for national flags and coats of arms of the former GDR to be placed almost anywhere in public places and institutions, not a single one was shown throughout the whole movie (except for one artistic representation of the CoA, with the hanging rope over it, on the cover of Der Spiegel magazine).
In 2006 the film was turned down by Dieter Kosslick and his selection jury for the Berlin International Film Festival.
The German DVD of this film was recalled due to some statements director Florian Henckel von Donnersmarck made in his audio commentary about the alleged activities of politician Gregor Gysi and actress Jenny Gröllmann as unofficial agents (IM) for the "Stasi" (secret police of former East Germany). New and old revisions of the DVD can be distinguished by a marking on the back spine (old retail/rental: Z4/Z4R, new retail/rental: Z4A/Z4S).
