An official site for David Fincher’s adaptation of the best-selling novel The Girl With the Dragon Tattoo has gone live, revealing detailed profiles for eighteen characters in the Swedish Noir thriller.

You can also now listen to an excerpt of Oscar-winning Social Network duo Trent Reznor and Atticus Ross’ soundtrack for Dragon Tattoo, which is already coyly selling itself as the “feel bad movie” of the upcoming holiday season.

There seems to still be some confusion as to whether or not Fincher’s Girl With the Dragon Tattoo is a direct remake of Niels Arden Oplev’s Swedish-language movie, or a fresh interpretation of the original source material (a la last year’s True Grit). Screenwriter Steve Zaillian has made it known that he intentionally avoided watching Oplev’s film while penning the script, so as to not be influenced by that version’s approach to streamlining the narrative material in Stieg Larsson’s popular novel. Likewise, the Dragon Tattoo teaser suggest the film will visually resemble Fincher’s previous work – and not the Swedish adaptation.

On that note – those of you who are completely unfamiliar with Girl With the Dragon Tattoo can get up to speed by checking out the new character profiles, which provide mug shots and succinct backstory information on the various players in the film. By and large, these are SPOILER-FREE.

The Girl With the Dragon Tattoo score

For those of you who have been anxiously awaiting the chance to hear what Reznor and Ross have cooked up for Fincher’s latest macabre murder mystery, here’s a preview of their score for Dragon Tattoo:

This particular piece has a very moody and foreboding sound to it, what with the synthesized wails and the occasional xylophone chimes. It’s should appropriately heighten the sense of unease that lingers throughout Dragon Tattoo, in between the bursts of disturbingly graphic violence and brutality that occasionally punctuate the story. Judging by Reznor and Ross’ previous collaboration on The Social Network, there should also be some catchily kinetic and heart-pounding themes included on the Dragon Tattoo soundtrack – for the brief bits of suspenseful action that pop up throughout the film.

As an additional treat: here’s an audio-only version of Trent Reznor and Karen O’s cover of Led Zeppelin’s “Immigrant Song”, which was used quite effectively in the Dragon Tattoo teaser trailer:

The Girl With the Dragon Tattoo arrives in U.S. theaters on December 21st, 2011.
