* DeletedScene: Forman's ''Director's Cut'' version has twenty minutes of extra scenes that were cut for pacing or in order to get a G rating. Many of them fill in minor PlotHoles.
** A scene after Cäcilia Weber (Constanze's mother) faints on-stage after the first performance of ''The Abduction from the Seraglio'' and Caterina Cavalieri angrily hits Mozart with a bouquet of roses. Salieri follows her to her dressing room and congratulates her. Mozart turns up and Cavalieri angrily says that Constanze "must be dazzling in bed" (much to Mozart's shock) and that's why Mozart is marrying her. This is how Salieri knows for certain that "the creature had had" his darling girl.
** A [[https://www.youtube.com/watch?v=eVR_sEFvBXk scene]] after Constanze shows up at Salieri's house and asks him to look at her husband's work and appoint him to the post. Salieri tells her to come back tonight alone and that a "service requires a service". She does so later on that night, and begins undressing. As she is standing there topless, Salieri suddenly rings for his valet to come and show her out.
*** This explains why Constanze is so rude and seemingly hostile ("what are ''you'' doing here?") to Salieri towards the end when she finds him sleeping close to Mozart, after having helped him write the Requiem. It also explains her sarcastic comment to him "I regret we have no servants to show you out, Herr Salieri".
** A [[https://www.youtube.com/watch?v=QQpH_FL93zE scene]] where Mozart arrives at a wealthy family's home in order to teach their teenage daughter to play the piano. The father has loads of dogs and they howl and growl as he plays. He gets up angrily and tells the man to let him know when he would [[SarcasmMode like him to teach one of his dogs again]].
*** Years later, he returns to the same man drunk and asks for to teach the daughter piano (since he is broke and needs the money). The father informs Mozart that the girl is married now and living in Mannheim. Mozart begs him for a loan of money and the man refuses and shows him out.
** Various small additional lines and shots.
* EnforcedMethodActing: While shooting the scene where [[spoiler: a dying Mozart dictates the Requiem to Salieri]], Tom Hulce deliberately skipped lines so as to make it seem [[spoiler: Salieri could not understand what he was being dictated]].
* FakeNationality: The Austrian Mozart and the Italian Salieri are played by Americans Tom Hulce and F. Murray Abraham.
* HeyItsThatGuy: That's a surprisingly young [[Series/SexAndTheCity Cynthia Nixon]] as the maid who comes to work for the Mozarts ([[spoiler:secretly hired by Salieri to spy on Wolfie]]).
** Creator/JeffreyJones, better known to most as [[Film/FerrisBuellersDayOff Principal Rooney]] or [[Film/TheHuntForRedOctober Skip Tyler]], plays Emperor Joseph.
** [[Film/AnimalHouse Pinto]] is Mozart!
* HeyItsThatVoice: Mozart is [[Disney/TheHunchbackOfNotreDame Quasimodo.]] That explains why Quasi can sing so well...
* TheOtherMarty: Meg Tilly was originally cast as Constanze Mozart, however, she tore a knee ligament the day before shooting started, thus being replaced with Elizabeth Berridge
* RevivalByCommercialization: According to TheOtherWiki, the film ironically helped spark a revival of Salieri's music, which had previously languished in obscurity.
* WhatCouldHaveBeen:
** Creator/MarkHamill was considered for the role of Mozart (for the film) and he had already played the role on Broadway. He was rejected because the director wanted lesser-known actors.
*** A little bit of a tangent, but interesting: When auditioning to voice [[WesternAnimation/BatmanTheAnimatedSeries the Joker]], he simply reprised his Mozart laugh from when he played the composer on Broadway. [[CaptainObvious It worked]].
** KennethBranagh, Tim Curry and Mel Gibson were among those rejected for the part of Mozart.
** Meg Tilly was originally supposed to play Mozart's wife but she injured her leg the day before filming and the part had to be recast. Director [[Creator/MilosForman Miloš Forman]] did later hire her again for a another period film set in the 18th century, ''Valmont'' (based on the novel ''Literature/DangerousLiaisons'').
