A United Kingdom

A United Kingdom tells the true story of Seretse Khama, heir to the throne of Bechuanaland, the territory that became Botswana, and Ruth Williams, a London office worker. The two meet in the late 1940s while Seretse is studying in England, and their decision to marry sets off opposition on several fronts. Their families object, the British government fears the diplomatic consequences, and South Africa, where interracial marriage was prohibited under apartheid, reacts with hostility. The couple's marriage becomes a matter of state, and their return home is complicated by exile and by the demands of the position Seretse is expected to take up.

Amma Asante directed the film, her second feature after Belle, followed later by Where Hands Touch. Guy Hibbert wrote the screenplay, and the producers include Rick McCallum, David Oyelowo and Brunson Green. Oyelowo plays Seretse Khama opposite Rosamund Pike as Ruth Williams-Khama, with Tom Felton, Jack Davenport, Terry Pheto and Laura Carmichael among a credited cast of 38. The production brought together companies from the United Kingdom, the United States, France and the Czech Republic, and its worldwide box office roughly matched its reported budget.

On IMDb the film holds a rating of 6.9 from around 18,000 votes, and on TMDB 6.6 from 553 votes, while a critics' rating stands at 6.7 from 161 reviews, placing professional and audience assessments close together.
