In ‘Blitz,’ Steve McQueen shows wartime London through a child’s eyes

It was a single photograph that started Oscar-winning filmmaker Steve McQueen on the journey to make “Blitz.” As a Londoner, the German bombing raids on the city during World War II are never all that far from his mind. Reminders of it are everywhere.

But the spark of inspiration came from an image of a small boy on a train platform with a large suitcase. Stories inspired by the evacuation are not rare, but this child was Black. Who was he, McQueen wondered, and what was his story?

The film, in theaters Friday and streaming on Apple TV+ on Nov. 22, tells the tale of George, a 9-year-old biracial child in East London whose life with his mother, Rita ( Saoirse Ronan ), and grandfather is upended by the war. Like many children at the time, he’s put on a train to the countryside for his safety. But he hops off and starts a long, dangerous journey back to his mom, encountering all sorts of people and situations that paint a revelatory and emotional picture of that moment.
