Bill Cunningham New York
I highly recommend watching this film which really gets into the mind and life of THE street style legend, Bill Cunningham. I can't even comprehend having such an active mind and acute eye for the things this guy sees.
Sadly the film never got a UK release but you can watch it online >HERE<. Just be warned you have to mute some crappy adverts which play next to the player once every twenty minutes or so!
