From W.H.Y. and Philadelphia, this is Fresh Air Weekend.

I'm Sam Brigger, Infra Terry Gross.

Today, screenwriter and director James Gray

talks about his new film, Armageddon Time,

inspired by his own experiences growing up

in a working-class neighborhood in Queens, New York.

His grandparents fled from anti-Semitism in Ukraine,

but his family didn't recognize their own biases

against black people.

He says the film is about the lesson
