Music. Power. Jealousy.
Lucian Msamati (Luther, Game of Thrones, NT Live: The Comedy of Errors) plays Salieri in Peter Shaffer’s iconic play, broadcast live from the National Theatre, and with live orchestral accompaniment by Southbank Sinfonia.
Wolfgang Amadeus Mozart, a rowdy young prodigy, arrives in Vienna, the music capital of the world – and he’s determined to make a splash. Awestruck by his genius, court composer Antonio Salieri has the power to promote his talent or destroy his name. Seized by obsessive jealousy he begins a war with Mozart, with music, and ultimately, with God.
After winning multiple Olivier and Tony Awards when it had its premiere at the National Theatre in 1979, Amadeus was adapted into an Academy Award-winning film.

Mary Stuart is imprisoned in England - nominally for the murder of her husband Darnley, but actually due to her claim to the throne of England held by Queen Elizabeth I. While Mary's cousin, Elizabeth, hesitates over signing Mary's death sentence, Mary hopes for a reprieve.
After Mary finds out that Mortimer (created by Schiller), the nephew of her custodian, is on her side, she entrusts her life to him. Mortimer is supposed to give Robert Dudley, the Earl of Leicester a letter from Mary, in which she pleads for help. This is a delicate situation, for Leicester seems to support Queen Elizabeth.
After numerous requests, Mary finally gains the opportunity to meet Queen Elizabeth (something that, in reality, never happened). This meeting ends in an acrimonious argument, caused by Mary's unwillingness to submit entirely to Elizabeth's wish. The argument leads to the inevitable suspicion that the cause of reprieve will not succeed.
To complicate matters further, Mortimer plans to free Mary from the prison by force, a dramatized version of the unsuccessful Babington Plot, but when his attempt is found out he commits suicide.
Queen Elizabeth eventually persuades herself to sign Mary's death warrant. Elizabeth insists that her only reason for signing is the pressure from her own people to do so.
The signed warrant is handed to Queen Elizabeth's undersecretary Davison without any clear instructions on what to do with it. In the process, Elizabeth transfers the burden of responsibility to him, fully aware that he in turn will hand over the warrant to Lord Burleigh, and thus confirm Mary's death sentence.
Burleigh demands the signed document from Davison, who - despite his uncertainty - eventually hands it to him. As a result, Burleigh has Mary executed.
The play ends with Elizabeth blaming both Burleigh and Davison for Mary's death (banishing the former from court and having the latter imprisoned in the Tower), Lord Shrewsbury (who pleaded for mercy for Mary throughout the play) resigning his honors and Leicester leaving England for France. Elizabeth is left completely alone as the curtain falls.

Since the original run, Shaffer has extensively revised his play, including changes to plot details; the following is common to all revisions.

At the opening of the tale, Salieri is an old man, having long outlived his fame, and is convinced he used poison to assassinate Mozart. Speaking directly to the audience, he promises to explain himself. The action then flashes back to the eighteenth century, at a time when Salieri has not met Mozart in person, but has heard of him and his music. He adores Mozart's compositions, and is thrilled at the chance to meet Mozart in person, during a salon at which some of Mozart's compositions will be played. When he finally does catch sight of Mozart, however, he is deeply disappointed to find that Mozart's personality does not match the grace or charm of his compositions. When Salieri first meets him, Mozart is crawling around on his hands and knees, engaging in profane talk with his future bride Constanze Weber .

Salieri cannot reconcile Mozart's boorish behaviour with the genius that God has inexplicably bestowed upon him. Indeed, Salieri, who has been a devout Catholic all his life, cannot believe that God would choose Mozart over him for such a gift. Salieri renounces God and vows to do everything in his power to destroy Mozart as a way of getting back at his Creator.

Throughout much of the rest of the play, Salieri masquerades as Mozart's ally to his face while doing his utmost to destroy his reputation and any success his compositions may have. On more than one occasion it is only the direct intervention of the Emperor himself that allows Mozart to continue (interventions which Salieri opposes, and then is all too happy to take credit for when Mozart assumes it was he who intervened). Salieri also humiliates Mozart's wife when she comes to Salieri for aid, and smears Mozart's character with the Emperor and the court. A major theme in Amadeus is Mozart's repeated attempts to win over the aristocratic "public" with increasingly brilliant compositions, which are always frustrated either by Salieri or by the aristocracy's own inability to appreciate Mozart's genius.

The play ends with Salieri attempting suicide in a last attempt to be remembered, leaving a false confession of having murdered Mozart with arsenic . He survives, however, and his confession is disbelieved by all, leaving him to wallow once again in mediocrity.
