Pathé has dropped the first trailer and poster for Gurinder Chadha’s Viceroy’s House, which stars Hugh Bonneville and Gillian Anderson and is based on the final months of British rule in India. They’ve set a March 3, 2017, UK release date.

Story is set in Viceroy’s House in Delhi, the home of British rulers of India. After 300 years, that rule is coming to an end and for six months in 1947 Lord Mountbatten, great grandson of Queen Victoria, assumed the post of the last Viceroy, charged with handing India back to its people. The story unfolds within this great house where the Mountbattens lived upstairs and downstairs lived their 500 Hindu, Muslim and Sikh servants. As the political elite converged on the house to wrangle overthe birth of independent India, conflict erupted.

The film’s UK release on March 3 coincides with the 70th anniversary of the Independence of India and the founding of Pakistan. It doesn’t have a U.S. distributor yet.
