Visible crew/equipment: When Mozart and family visit a parody on several operas of his in a public theater, in one part of the show little people appear from all sides of the stage. When the last of the little people (carrying a model of horse) hops through a paper wall on the side of the stage, you can see a man in jeans walking behind the set.

Continuity: When Salieri has brought Mozart to bed and they are talking, Salieri is holding the candlestick. In the different views - from Mozart's and Salieri's - it can be seen that the angle he holds the candles changes. The line between the candles changesi. So Saleri held the candlestick in another angle the second time the scene was shot.

Visible crew/equipment: Mozart is composing The Requiem Mass when Constanze admits a late-night caller. The door she opens reflects a large, bright square of light that looks like a sun-lit window (only it's night) - or more likely, a studio reflector. (It's definitely not the burning candles. Wrong shape.).

Continuity: When Mozart is playing billiards (Director's Cut only) the balls move around on the table between camera shots, without him necessarily hitting any.

Continuity: In the scene where Salieri is helping Mozart with the requiem the candles change appearance - and not just downwards because they burn.

Continuity: In the extended version of the DVD, there's a scene where Constanza goes to sleep with Salieri. In one shot there's a very prominent candle next to or just behind her on her right that smoking like it's just been extinguished. But from the front view there are no candles that close to her, and the ones a short distance away are all lit.

Continuity: In the opening scene when Salieri's servants offer him ice cream and cakes, the choppy servant gets ice cream on his nose. When seen from behind there is more ice on his nose than when seen from the front.

Continuity: Mozart's pianoforte is carried outside for the concert. But while the concert is going on, Salieri goes to Mozart's home, and the just-carried-out piano is still there.

Factual error: During the ballet scene in the Marriage of Figaro, many of the costumes worn by the dancers have visible zips on them, which of course had not been invented then.
