From director Amma Asante (Belle), starring David Oyelowo (Selma) and Rosamund Pike (Gone Girl) and set against the breath-taking backdrops of the African savannah and period London, A United Kingdom celebrates the inspiring real-life romance of Seretse Khama, King of Bechuanaland (modern Botswana), and Ruth Williams, the London office worker he married in 1948 in the face of fierce opposition from their families and the British and South African governments. One of the greatest love stories ever told.
