Has anyone seen a documentary (maybe this is it, but from the description I don't think so) which includes the Insane Clown Posse and Noam Chomsky? From what I remember, it's a movie about commercials and marketing and fads. Noam Chomsky is featured in a couple of interview segments, ICP shows up when they are talking about anti-consumerism (though then they mention that ICP later "sold out" or something like that).
shareThis is not that documentary. ICP is definitely not in it, but if you're at all interested you should absolutely check this movie out. Honestly, it will really change the way you look at the world.
FREE TIBET!
The Documentary you are referring to is probably "PBS: The Merchants of Cool":

I saw it recently, I remember for sure that ICP was in it and how they sold out for signing a major record label while to their nascent Detroit fanbase they were mouthing off un-geniune corporate backed musicians.
However, I cannot recall Chomsky being in the film.
