Amadeus (1984)

Factual error: During the scene where Mozart is being carried away in his coffin by horse and cart there is a brief shot where he is being taken down a muddy path and a farmer is seen with his cows. If you look closely to the left side of the screen you can see a large overhead power line. If you look even more closely you can even see the wires coming out of the pylon. The movie is set in the 18th century and obviously it should not be there. (02:50:50)

Antonio Salieri: But why? Why would God choose an obscene child to be His instrument? It was not to be believed! This piece had to be an accident. It had to be.
Antonio Salieri: ...It better be.

Trivia: The actors in the film are never actually heard playing the keyboard instruments. The actors played the keyboards in time to recorded music being played on set or via earphone. However, in order to avoid mistake watchers noticing it, the actors had to learn the pieces, so that they are almost always playing the right keys for the music.
