It was shot by inventor and film pioneer William Friese-Greene on celluloid film using his 'machine' camera. The 20 feet of film, which was shot in autumn 1889 at Apsley Gate, Hyde Park, London, was claimed to be the first motion picture, although Louis Aimé Augustin Le Prince successfully shot on glass plate before 18 August 1887, and on paper negative in October 1888. It may nonetheless be the first moving picture film on celluloid and the first shot in London. It was never publicly screened, although several photographic journalists saw it during his lifetime — including Thomas Bedding, J. Hay Taylor and Theodore Brown. It is now considered a lost film with no known surviving prints and only one possible still image extant.
