War and Peace is a British television dramatisation of the 1869 Leo Tolstoy novel War and Peace. This 20-episode series began on 28 September 1972. The BBC dramatisation of Tolstoy's epic story of love and loss set against the backdrop of the Napoleonic Wars. Anthony Hopkins heads the cast as Pierre Bezukhov, Morag Hood is Natasha Rostova, Alan Dobie is Andrei Bolkonsky and David Swift is Napoleon, whose decision to invade Russia in 1812 has far-reaching consequences for each of them and their families.
The twenty-part serial was produced by David Conroy and directed by John Davies. Conroy's aim was to transfer the characters and plot from Tolstoy's novel to television drama to run for a duration of 15 hours. Scripted by Jack Pulman, this version of War and Peace contained battle sequences, which were filmed in Yugoslavia.
