!!For the 1932 Film:
* AdaptationDisplacement: Of both the novel and the stage play based on it.
* AlternativeCharacterInterpretation: Was the Baron actually in love with Grusinskaya? Or did he just say that to prevent her from committing suicide and was merely being polite afterwards?
** TheMusical gives them a love duet and explicitly paints the two as being deliriously in love.
* AwardSnub: Creator/JoanCrawford and Creator/JohnBarrymore weren't nominated for Best Actress and Best Actor at the UsefulNotes/{{Academy Award}}s.
* EnsembleDarkhorse: Even though the movie is more famous for Creator/GretaGarbo's "I want to be alone" line, some newer viewers find themselves being pleasantly surprised by Creator/JoanCrawford's performance--finding her to be superior to Garbo. This was the case on set too, as Garbo was brought back in to shoot additional scenes to beef up her role, after Crawford impressed.
* SugarWiki/HeartwarmingMoments: Flaemmchen waits at the bar for the Baron. He arrives and, after a brief dance, asks her to continue dancing with Kringelein instead. Rather than getting annoyed or jealous, she agrees and does something so nice for a poor old man who doesn't have much time left.
* MemeticMutation: "I vant to be alone," thanks to it fitting so well with Creator/GretaGarbo's sudden retirement from public life. Garbo emphasized that the press had conflated this line with what she'd said in interviews at the time: "I want to be ''left'' alone," quite a different matter.
* MoralEventHorizon: [[spoiler: Preysing]] crosses this when he [[spoiler:kills [[GentlemanThief the Baron]] just because he was trying to steal his pocket book]].
* NarmCharm: Some of Greta Garbo's rather over-the-top mannerisms are amusing, yet they fit her character's emotional state and are quite proper for a White Russian artiste at that time.
* SoOkayItsAverage: This movie has been used as an example of the Academy's questionable judgment in early years--not exactly bad, but it didn't age well.
* TearJerker:
** The scene where Kringelein thinks he's lost his pocket book (after having won an enormous amount of money gambling), when the Baron has taken it to pay off his debts. As he desperately searches for the book, the Baron ultimately can't bear to steal it and gives it to him saying he just found it.
** After [[spoiler: the Baron's death]] Flaemmchen agrees to be Kringelein's companion in an attempt to be positive. But when they go to ring for a train ticket, they both nearly collapse in tears--still devastated.
* WatchItForTheMeme: Some watch it just to hear the famous Garbo quote.
* TheWoobie: [[SecretlyDying Kringelein]] and [[spoiler: [[DrivenToSuicide Grusinskaya]], {{in|terruptedSuicide}}itially.]]

!!For the stage musical:
* HilariousInHindsight: The theory on the Fridge page about the Creator/TakarazukaRevue Bolero being a dance between the Baron and Death gets funnier with the knowledge that Tamaki Ryou (2017 Baron) has played Death in both ''Theatre/RomeoEtJulietteDeLaHaineALamour'' and ''Theatre/{{Elisabeth}}'', opposite Manaki Reika (2017 Elizaveta) as Juliette and Elisabeth, respectively. The Doctor's line about Love and Death coming face to face would be taken literally in ''Roméo et Juliette'', as Love [[note]]created specifically for the Takarazuka productions[[/note]] and Death are both characters who spend much of their stage time dancing with each other. ''Elisabeth'' contains the song "The Rondo of Love and Death" (Ai to Shi no Rondo), in which Death falls in ''love'' with Elisabeth and decides not to take her soul. If only the Baron was that lucky.
* OlderThanTheyThink: This musical uses songs from an older attempt to bring ''Grand Hotel'' as a musical, however this version called ''At The Grand'' was set in contentary Rome and did get mixed reviews and great audiences but one of the leads Paul Muni was ill and so the Producer cancelled the Broadway run.
* UnintentionallyUnsympathetic: The Doctor comes across as callous when he dismisses the pain of Erik's wife (going through childbirth) as lesser than war wounds.

!!For the 2019 Series:
* TheScrappy: Ingrid. Carolina too.
