Steve McQueen is the director of four feature films, including the Oscar-winning “12 Years a Slave.” His new series, “Small Axe,” which is streaming on Amazon, consists of five portraits of the West Indian community in London from the late nineteen-sixties through the nineteen-eighties. For McQueen, the stories allowed him to reflect on painful aspects of his own upbringing in that time and place—like the way many children of immigrant families were shunted into “subnormal” schools. “I wanted to feel that I exist,” McQueen tells Richard Brody. “This is part of the narrative of the world, part of the narrative of life. And sometimes things like that never get seen or never get noticed or never get the recognition.” Plus, the staff writer Larissa MacFarquhar on what happens to families in Haredi Jewish communities when one parent leaves the faith.
