Bill Cunningham is a fashion monk. Now over 80, the legendary New York Times street-style photographer has ridden his bike round Manhattan for decades snapping away, while living an ascetic life of $3 lunches. Honoured by the fashion elite (even steely Vogue editor Anna Wintour brims with praise), he’s undazzled by celebrity. After years on his trail, director Richard Press unearths hints of the complex reasons the humble fanatic – exuberant with eccentricity and old-fashioned kindness – denies himself a private life in a doc that’ll make more than just fashionistas smile.
