Culloden (known as The Battle of Culloden in the US) is a 1964 docudrama written and directed by Peter Watkins for BBC TV. It portrays the 1746 Battle of Culloden that resulted in the British Army's destruction of the Scottish Jacobite rising of 1745 and, in the words of the narrator, "tore apart forever the clan system of the Scottish Highlands." Described in its opening credits as "an account of one of the most mishandled and brutal battles ever fought in Britain," Culloden was hailed as a breakthrough for its presentation of a historical event in the style of modern TV war reporting, as well as its use of non-professional actors. The film was based on John Prebble's study of the battle.[1]
