David Oyelowo has been acclaimed for his performance as Martin Luther King, Jr. in Selma, as well as diverse dramatic roles from Red Tails and The Paperboy to Lee Daniels' The Butler (as the radicalized son of Forest Whitaker) and Queen of Katwe. His stage work includes the title role in the recent Othello (with Daniel Craig as Iago) for the NY Theatre Workshop.
A United Kingdom is based on the true story of Seretse Khama, an African prince who fell in love with a white British woman (Rosamund Pike) in the late 1940s. Their marriage sparked international controversy, especially given Britain's economic interests in neighboring South Africa, which was implementing apartheid. Like director Amma Asante's previous film Belle (2014) — about a female aristocrat of mixed English and African ancestry — it explores historical tensions of race and romance.
