Based on the lives of Botswana’s first president Seretse Khama and his British wife Ruth Williams Khama, A United Kingdom stars David Oyelowo and Rosamund Pike, and spoiler alert: Its new trailer will make you cry. Oh, you might think you’re immune to sweeping romances, anti-colonial freedom fighting, and biopics that tug at your heart strings, but just you wait until you see that big, fat, beautiful baby of theirs. The film, from Amma Asante, the director of Belle, tells the story of a rare interracial romance in 1940s England, and the way it played into Botswana’s independence movement. The film is a passion project for Oyelowo, who convinced Pike to join the film by sending her photos of Seretse and Ruth, and, if you had to guess, their big, fat, beautiful baby. The film is scheduled to premiere February 17, 2017.
