King John is the title by which the earliest known example of a film based on a play by William Shakespeare is commonly known.
Filmed in London, England, in September 1899, at the British Mutoscope and Biograph Company's open-air studio on the Embankment, it was a silent film made from four very short separate films. Each of those films showed a heavily edited scene from Herbert Beerbohm Tree's forthcoming stage production of Shakespeare's mid-1590s play, King John, at Her Majesty's Theatre London.
The first film was of The Temptation Scene with John, Hubert, and Arthur, the second of The Lamentation Scene with Constance, Philip of France, Lewis, and Pandulph, the third of King John's Dying Scene with John, Henry, Pembroke, and Salisbury, and the fourth of King John's Death Scene with John, Henry, Falconbridge, Pembroke, and Salisbury. The filming of King John was produced and directed by William Kennedy Laurie Dickson and Walter Pfeffer Dando. The acting and production design was by Herbert Tree, the cinematography was by William Dickson, and the production company was the British Mutoscope and Biograph Company.
The EYE Film Institute Nederland has an incomplete copy of the third film lasting just under one minute. The last seconds of the scene are missing from the EYE copy; the BFI National Archive has a film clip of a few frames of the missing part.
The below still frames from the film were published in the 27 September 1899 issue of The Sketch accompanying a review of Tree's stage production. While these were known to scholars ever since Robert Hamilton Ball's Shakespeare On Silent Film (1968), and preceding journal papers, they were assumed to be ordinary production stills from the stage adaptation. It was not until B. A. Kachur's paper "The First Shakespeare Film: A Reconsideration and Reconstruction of Tree's King John" (1991) in Theatre Survey that they were identified as still frames from the film.
