This is a documentary about one of the most famous and talked about filmmakers of all time. It features interviews and fan films about the Star Wars saga that were submitted to the documentary's website, apparently making the documentary the first "digitally democratic feature". At about 1:08 in this trailer, I think the animation is from NG's LegendaryFrog. There might be other NG animations I'm not familiar with in all three trailers. Anyway, if you're interested in seeing this film, visit the website and look for festivals it's playing at near you. You can also demand it like Paranormal Activity.
