'Bill Cunningham New York'

Poster is fair enough. Busy, but okay. The San Francisco Chronicle calls it 'deeply moving, visually stunning'. Not sure how that could be, but I'm intrigued.

IMDb has:

An intimate portrait of Bill Cunningham, the 80 year old New York Times photographer who for forty years has been riding around New York City on his bicycle, documenting fashion trends on the street by day and New York's social scene at night for his two weekly columns in the Sunday Times. Known and beloved by most New Yorkers, and with an international following in the paper and on-line. Bill has been likened to Garbo in that, until now, no one has known a thing about him. Intensely private, and with an aversion to any kind of recognition.

Here's the NYT listing for Cunningham.
