Edward Norton's favorite movie

If not for Norton's recommendation I may never have seen it. One of the greatest doco's I've ever seen (Up there in my favourites with the likes of Grey Gardens (1975), Man with a Movie Camera (1929), Hoop Dreams (1994), Crumb (1994), Grizzly Man (2005), Sans Soleil (1983), Baraka (1992), Samsara (2011), Dark Days (2000) etc.) and yet it is simply 75 minutes of one man in New York City. Great choice by Norton, it looks like he's seen a lot of films (couldn't say the same for all of those appearing in 'Top 5' videos by RT, though some others are good).

Is this your homework, Larry?
