* AlternateCharacterInterpretation: To what extent was Alex's charade done out of love and overzealous concern for his mother, versus nostalgia for the past and his suddenly-lost country?
* ArtisticLicenseHistory: Assuming the cab driver really ''is'' supposed to be Sigmund Jähn, this could count. In real life, Jähn had managed to work as a freelance consultant for the German Aerospace Center (DLR) following reunification in 1990, prior to which he was in the East German army where he had risen to the rank of Major General, hardly making him likely to be as down on his luck as the movie suggests.
* CrowningMusicOfAwesome: During [[spoiler:'President' Jähn]]'s address to the nation, the national anthem of East Germany plays in the background, and then swells to a crescendo as the scene shifts [[spoiler:to the Reunification celebrations]].
** [[https://www.youtube.com/watch?v=6mo59IyQbro&list=RD6mo59IyQbro#t=3 The main theme]], which plays when Alex's mother sneaks out and sees for herself how Berlin has changed.
** And the short, [[TearJerker but touching]], [[https://www.youtube.com/watch?v=-RxkxCj4cpc piano piece at the beginning and end of the film]] (Summer '78).
* TearJerker: Several moments, but the biggest is the ending, [[spoiler: when Alex and the others hold a funeral for his mother and he comments on how he'll remember her and the country she was part of and died with. All while old footage of East Germany streets and his mother and sister at summer camp is shown]].
