Whether this is an actual trailer release from Fincher or a bootlegged cam version is still up in the air. For a bootleg source it is incredibly sharp and the audio sounds very clear which is usually not the case with these type of things. Also the video is still up on YouTube and gone over 1.5 million hits making it more like that this is a studio viral stunt. Either way this is a very cool trailer. I’m especially digging the Reznor remake of Immigrant Song over the top of the trailer. It really gives us a good sense of what this movies gonna be about.
