Peter Shaffer, English playwright and screenwriter; works included Equus and Amadeus (born 1926)

Sir Peter Levin Shaffer was an English playwright, screenwriter, and novelist. He is best known for the plays Equus and Amadeus, the latter of which was adapted for the screen by Miloš Forman, with an Academy Award–winning screenplay by Shaffer.

Equus is a 1977 psychological drama film directed by Sidney Lumet and written by Peter Shaffer, based on his 1973 play of the same name. The film stars Richard Burton, Peter Firth, Colin Blakely, Joan Plowright, Harry Andrews, Eileen Atkins, Kate Reid and Jenny Agutter. The story concerns a psychiatrist treating a teenager who has blinded horses in a stable, attempting to find the root of his horse worship.

Amadeus is a 1984 American period biographical drama film directed by Miloš Forman, starring F. Murray Abraham and Tom Hulce. Peter Shaffer adapted it from his 1979 stage play Amadeus, originally inspired by Alexander Pushkin's 1830 play Mozart and Salieri. Shaffer described it as a "fantasia on [a real-life] theme", as it imagines a rivalry between two 18th century Vienna composers, Wolfgang Amadeus Mozart (Hulce) and Antonio Salieri (Abraham). Salieri struggles to reconcile his professional admiration and jealous hatred for Mozart, and resolves to ruin Mozart's career as his vengeance against God.
