The account is loosely drawn from the final two years of Vladimir Lenin's life, during which he lived in a controlled environment similar to that depicted in the film. On the grounds that excessive excitement could jeopardise Lenin's health, Joseph Stalin had single-copy editions of newspapers printed for him, with all coverage of the period's political struggles excised by censors.
Extensive CGI was employed to "de-Westernise" Berlin. Although most of the film was shot in the former East Berlin and much of the story takes place after the fall of the Wall, the city had been Westernised at a furious pace. Many advertisements for Western products had to be removed, and numerous colours were noticeably lightened or greyed.
Sigmund Jähn granted permission to appear in the film but declined to portray himself. Finding an actor who resembled Jähn and spoke his characteristic dialect proved very difficult, but once filming was underway Wolfgang Becker selected Swiss actor Stefan Walz. He was fitted with elaborate make-up and was dubbed by another actor from Jähn's native Vogtland.
The bank scene was filmed on 11 September 2001. Maria Simon later said she found it very difficult to separate performing from the astonishing TV news coming from the real world.
The reason Denis (Florian Lukas) is shown wearing a T-shirt that resembles the computer code from The Matrix (1999) is that there was originally a scene in which he talked about a film idea of his called "Planet of the Forgotten", which closely mirrored the plot of The Matrix (1999). That scene can be viewed among the deleted scenes on the DVD.
As Chulpan Khamatova didn't speak sufficient German to improvise properly, she had to memorise her (grammatically correct) lines word for word. Because that sounded unnatural, all her lines were translated into Russian and then translated back verbatim to recreate a natural Russian accent with the characteristic grammatical mistakes.
During the birthday gathering, when Rainer (Alexander Beyer) attempts to conceal his West German background from Christiane, he nearly blurts out that he was a Gauleiter in the children's Pioneer organisation. A Gauleiter was the title used for a regional leader of the Nazi Party.
This film is featured in the book "1001 Movies You Must See Before You Die", edited by Steven Schneider.
Russian novelist Olga Slavnikova published the bestselling novel "Bessmertnyj" in October 2001, whose plot bears notable similarities to the film "Good Bye Lenin!". The story follows an elderly resident of Yekaterinburg, a paralysed veteran of the Second World War. His daughter seeks to make his life easier by constructing an alternate reality ruled by the Soviet Party, which involves recreating video material about the USSR. The man dies of an infarct. Because of these resemblances, Slavnikova announced she intended to sue the creators of "Good Bye Lenin!" for plagiarism. No trial, however, took place — Russian media had also advised her against pursuing legal action. Moreover, filming was already under way when the book appeared, which indicates the screenplay existed before the novel was released.
Nowhere in the film is it stated, but the family's flat is situated in the Friedrichshain district of East Berlin.
At a 2009 press conference for his film "Inglourious Basterds", Quentin Tarantino briefly mentioned that a friend of his — the German director Tom Tykwer ("Cloud Atlas", "Run Lola Run", "Perfume") — had offered, when Tarantino enquired whether he knew anyone who could translate the German portions of the dialogue for the English subtitles, to do the translation himself because he already understood what Tarantino wanted. Tykwer also recommended that Tarantino watch "Goodbye, Lenin!", starring Daniel Brühl, which promptly convinced Tarantino that Brühl was the right actor to play Fredrick Zoller in "Basterds", and he subsequently cast him in the role.
The building used for Alex (Daniel Brühl) and Denis (Florian Lukas) in their 'Coca-Cola' news segment is the same location that Billy Wilder employed for his 1961 film One, Two, Three (1961).
In the original script, Denis (Florian Lukas) was a heavier-set Turkish–German called 'Deniz'.
Florian Lukas had initially been cast to play Alex. When director Wolfgang Becker selected Daniel Brühl for that part, he offered Lukas the part of Denis.
The helicopter seen flying past Alex's mother (played by Daniel Brühl) and bearing a statue of Lenin is a Mil Mi-8 transport helicopter that was widely used throughout the Warsaw Pact countries. In the GDR it was employed specifically as a flying crane.
All the letters in the film Good Bye, Lenin! (2003) were penned by a young woman from Cologne who was on placement with the production crew.
Jürgen Vogel appears twice in the film. First he has a cameo as one of the arrested demonstrators (front row, wearing a blue jacket), and later he turns up as the chicken in the supermarket — a nod to Wolfgang Becker's earlier film Life is All You Get (1997) — for which he is credited as "Das Küken" ("young chicken").
For most of the film, Alex (Daniel Brühl) is seen wearing a T‑shirt bearing the pre‑reunification logo of Motorradwerk Zschopau, the company better known as the MZ motorcycle manufacturer.
In a deleted scene, Lara (Chulpan Khamatova) identifies herself as "Lara, like in Doctor Zhivago," a film that, incidentally, also portrays "a futile struggle to preserve the past."
Although Alex had trouble sourcing Spreewäldgurken, they were actually one of the few East German products that stayed continuously available following Germany's reunification in 1990.
As in Billy Wilder's One, Two, Three, the story is set in Berlin and revolves around the Berlin Wall; both films feature the concealment of political truth: in Good Bye, Lenin! someone is kept unaware that Communism has collapsed, whereas in One, Two, Three a young woman hides from her capitalist father that her fiancé is a die‑hard Communist.
