Four years after its release, I finally rented the Beastie Boys concert film Awesome; I F--kin' Shot That! The interesting thing about the film is that it was mostly shot by amateurs. 50 concertgoers were handed Hi8 cameras, and the film was compiled primarily from that grainy, shaky footage. In a way, the concept is not much different from a lot of archive-dependent documentaries, which also pick their material from content produced by others. The fact that it was more pre-planned and focused doesn't conceptually separate it from the film that could have been made from found footage shot by fans on personal cameras and phones (this type of fan-made video actually inspired the film to begin with). And like those documentaries consisting of mostly old, appropriated clips and stills, Awesome is only as good as its editing and post-production effects.
What may be distinctive about this film is that it involves crowdsourcing rather than licensing. Certainly some documentaries could gather up footage that's in the public domain or cost-free by way of fair use, but otherwise there's a matter of paying for the content employed in the film. If someone was making a documentary about Hurricane Katrina and wanted to incorporate a home video shot during the storm that you uploaded to YouTube, they'd have to at least get permission if not also (preferably) pay you for the usage. Crowdsourcing is more like Wikipedia in that it gets people to do the work for free right from the get go.
