David Fincher now believes in viral marketing! The Girl with the Dragon Tattoo, which will be hitting theaters just in time for Christmas, first had a bootleg trailer that sold Daniel Craig and Rooney Mara in the film with the sort of fast cutting one expects of Fincher. Now they’ve released an extended trailer (not intended for theaters) that sets up the entire film. Check it out.

This lays out the plot of the film fairly cleanly. An old murder, a late stage attempt at solving it, powerful and weird people who might be behind it, and Lisbeth Salander (Mara) – the investigator who is unconventional to say little else. The books were a phenomenon – much like The Da Vinci Code or The Firm – and that usually translates to a big hit. It’s unknown if the holiday season release will help or hurt.

This gives a very clean set up to the film and the relationship between Craig and Mara, with hints at what she’s going through. And with the elaborate mystery revolving around someone’s death, it suggests Fincher is in his wheelhouse. It looks and sounds great (and you can hear composer Trent Reznor in soundtrack), and at this point the question is: is it also an awards picture? We’ll know for sure come 12/21.
