New Girl With the Dragon Tattoo Mega-Trailer: What Have We Learned?

What can you get from eight minutes that you can't get from three? You'd be surprised...

We've thanked Trent Reznor for a lot of things over the years, but today, we're thanking him for the eight-minute trailer for The Girl With the Dragon Tattoo that he linked to last night.

Rooney Mara, Daniel Craig, a bunch of your other favorite Brits and Swedes and the haunting, pitch-perfect score by Reznor and Atticus Ross (composed specially for the trailer!) have combined for quite the ride, one that significantly expands on the relatively puny three-minute teaser released a couple months ago.

Seriously, it's like watching a whole movie—one that gets us so pumped for the real whole movie, in theaters Dec. 21, that is. And here's what we know now, based on those five extra minutes:

Get comfortable.

This movie is sticking to the source material like nobody's business. Giving eight minutes and 24 seconds of suspense and drama away now is apparently nothing when your movie is almost three hours long. That's just a projection, mind you, based on how much detail is packed into the script, from all of the craziness Lisbeth Salander (Mara) goes through apart from the central murder mystery to the meticulously detailed flashback sequences.

Don't let The Social Network fool you. You saw Seven, right?  

David Fincher's proposed trilogy is going to be just as violent as the Swedish-language trilogy (GWTDT was directed by Niels Arden Opley, while Daniel Alfredson helmed The Girl Who Played With Fire and The Girl Who Kicked the Hornet's Nest). While the trailer has obviously been pared down for "mature audiences," based on the crime-scene photos glimpsed (not to mention our knowledge of what's coming based on the book), we just know that Fincher is going to go all-out with the grotesquery.

Although the trailer's score was just a little something Reznor and Ross knocked off in their spare time, the Dragon Tattoo soundtrack should easily net the Oscar-winning pair another nomination.

We know this because, in addition to the trailer, Mr. Nine Inch Nails himself also linked to his and Karen O's cover of Led Zeppelin's "Immigrant Song," available free when you preorder the soundtrack.

And, for that, we thank him again.
