I don't think any other city actually has anyone who has actually documented the way they have lived or documented the city themselves. If you want to look at New York in the last half of the 20th century, into the 21st, you would look at Bill Cunningham's archives.

I first started making films - this is my first feature, but I was making shorts - I was actually freelancing as a day job at The New York Times as an art director. I actually worked with Bill Cunningham and really soon after I met him, I thought, Oh my God, he's a perfect subject for a documentary.
