Macbeth

Macbeth was a play, as well as the name of the titular regicidal thane, created by William Shakespeare.

On 5 November 1605, the script of Macbeth was on a balcony of the Houses of Parliament. (GAME: The Gunpowder Planet)

Robert Dodds believed his role as Banquo in the play to be his greatest triumph; most thought he was a poor actor. He was killed by Pamela whilst reciting his lines from the play. Two plaques with speeches from the play adorned Dodds' home, Banquo Manor. (PROSE: The Banquo Legacy)

During both his sixth and eighth incarnations, the Doctor superstitiously referred to it as "the Scottish Play". (AUDIO: Medicinal Purposes, The Next Life, The Book of Kells)
