Nominated for 4 oscars, Kubrick's A Clockwork Orange gained notoriety because he insisted that it was withdrawn from public viewing in the UK due to the extreme violence. As the press releases said, it was the story of a young man whose primary interests were rape and Beethoven. Note that this poster is from the short lived UK release of the film - it was only showing for six weeks - so this original country-of-origin poster is particularly rare.
Philip Castle's iconic artwork on this British poster was used in the international poster campaigns. This is very rare, as normally each domestic market created their own posters.
Although Stanley Kubrick's disturbing film was released uncut in the UK in 1972, the film was then withdrawn in 1973 at the request of Kubrick. The film had been linked to a couple of horrific copycat crimes, and during the trials A Clockwork Orange was cited by one of the prosecutors. There were also protests outside Kubrick's home, and him and his wife had received threats. The film did not get a further theatrical release until 2000, the year after Kubrick's death.
