On the DVD you can watch the making of the movie, and it includes Larry Clark looking old.
scene from the movie, for no reason:
scene of Bijou Phillips when she is not naked:
A photo of the old man:
I was reading about him a little bit on the internet, I learned that he made a photo book of his friends having sex and using drugs back the the 60s or something like that, and it influenced Martin Scorcese making "Taxi Driver." So, he may be old, but if he influenced "Taxi Driver" then he is cool.
*edit-won't link to Bijou Philips image! Sorry. It was a pretty sleazy pic, too.
