* CaliforniaDoubling: 18th century Vienna was shot in 1980s Prague - because their roofs don't have lots of satellite dishes that could potentially spoil the shot.
* 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 rude to Salieri in later scenes.
** A [[https://www.youtube.com/watch?v=QQpH_FL93zE scene]] where Mozart arrives at a wealthy family's home to teach their teenage daughter to play the piano. However, the father also has loads of dogs who howl at music, and he insists that they stay as Mozart plays so they can be broken of the habit. Mozart eventually cuts off the lesson and curtly requests the man contact him [[SarcasmMode should he need a second lesson for his dogs]]. A CallBack scene has him returning to the same man and drunkenly beg for a job.
* EnforcedMethodActing: Hulce also 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 Creator/FMurrayAbraham.
* RevivalByCommercialization: According to Wiki/TheOtherWiki, the film ironically helped spark a revival of Salieri's music, which had previously languished in obscurity.
* ThrowItIn: In the scene when Mozart is dictating the Requiem to Salieri, the audio playback suffered technical difficulties; however, since Mozart is supposed to be delirious with fever, Hulce played his reactions in character and this made it into the final cuts.
* 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.
** Creator/KennethBranagh, Creator/TimCurry and Creator/MelGibson were also among those rejected for the part of Mozart.
** Meg Tilly was originally supposed to play Mozart's wife Constance, but she injured her leg the day before filming and the part had to be recast. Director Creator/MilosForman did later hire her again for a another period film set in the 18th century, ''Valmont'' (based on the novel ''Literature/DangerousLiaisons'').
