UK drama has working class Brits simmering under racial tensions: in the warehouses, the factories, even at the public pool--the catalyst being a hard-working black man who gets a coveted factory promotion over the petty, envious whites (wasn't this the same situation in "Black Legion" from 1937?). John Mills plays a union organizer who tries bringing peace to the locals but is confounded by the unexpected romance between his white daughter and a black teacher from the West Indies. Ted Willis adapted his play "Hot Summer Night", forgetting that screen material needs to be less theatrical, more subtle and sensitive. Each character spouts off with such pedagogic fervor, vigorously puffed up with their own righteous anger, that the main theme of tolerance is diffused (with that faux-calypso music playing, you'd think there would be more dancing than feuding!). OK melodrama, it beat "Guess Who's Coming To Dinner?" to the screen by several years, and a few of the performances are thoughtfully rendered. Color film released by the The Rank Organisation was distributed to the States by Atlantic Pictures in black-and-white. ** from ****
