Synopsis for
Amadeus (1984) More at IMDbPro »

It is a cold winter evening and a houseman attempts to rouse his master, former glorified Vienese court composer Antonio Salieri. Being unsuccessful knocking, they force Salieri's bedroom door opne and find him on the floor, bleeding from a knife wound to the neck. They carry him to a mental hospital, where his wound is bound up, and a priest comes to see him the next day. The priest attempts to get him to explain why he would try to take his own life and the movie flashes back, with Salieri narrating, to how he met Mozart and became insanely jealous of his talent. Tom Hulce plays Mozart and F. Murray Abraham plays Salieri. Cynthia Nixon, Jeffrey Jones, and Roy Dotrice also co-star.

Amadeus is a work of fiction - not a biography.

From Wikipedia. Amadeus is a stage play written in 1979 by English author Peter Shaffer, loosely based on the lives of the composers Wolfgang Amadeus Mozart and Antonio Salieri. Amadeus was inspired by Mozart and Salieri, a short play by Aleksandr Pushkin and later adapted into an opera of the same name by Nikolai Rimsky-Korsakov. Shaffer then adapted the play for a film released in 1984.

Significant use is made of the music of Mozart, Salieri and other composers of the period.
