Christopher Nolan On Harry Styles

Director Christopher Nolan didn't know quite how famous Harry Styles was before "Dunkirk." On Friday Nolan admitted that before casting the pop star in the upcoming World War II epic, "I don't think I was that aware really of how famous Harry was...my daughter had talked about him." As for Harry Styles, he says, "I'd say realizing the scale of the production was very overwhelming...it was pretty amazing."
