It could be some brilliant marketing by Sony and Columbia Pictures...because if it's pirated, why hasn't it been taken down yet? And how did the sound get so good? It's the trailer for the highly-anticipated "Girl With the Dragon Tattoo" movie complete with a taste of Trent Reznor's soundtrack, a remake of Led Zeppelin's "Immigrant Song" with Karen O on vocals.

We could be enabling the studio by spreading the news, but then again, Who cares? It looks pretty cool.
