I thought I saw a reference to this, but after searching (even with Google), I couldn't find it.
I just watched this film - not bad! It's amateur-ish and goofy at times, but they tour 38 craft breweries in 40 days, and it includes some great interviews.
Breweries include: Dogfish Head, Anchor, Red Hook, Climax, Anderson Valley, Rogue, New Belgium, and a ton more that have slipped my mind (because I tried to keep up with the guys in the film...beer drinking, that is).
Worth a look - especially if you have Netflix or other cheap means of renting a movie.
