Holy cow is this an excellent documentary. For those of you who haven't heard about this, it's available in select theaters and for rent/purchase on iTunes/Vudu. George Romero is the only participant from NOTLD to be featured, however the panel of guests that speak about the impact of the key scenes as well as the movie itself are amazing. It comes in at around 90 minutes but it really does the film justice as well as the state of America in the late 60's. The trailer is also currently available on the Apple trailers site. I highly recommend this. Lastly, if you watch it, there is a nice tribute to Bill Hinzman after the credits.
