David Fincher's adaptation of The Girl With The Dragon Tattoo is really taking shape. Nearly every puzzle piece is in place and the crew is already set up and in the midst of filming in Sweden. Only it seems they have forgotten one of the key pieces to the murder mystery: the victim. That changes today.

Just Jared reports that Alexandra Daddario will play the young Harriet Vanger in the English language film based on the novel by Stieg Larsson. In the story, the young Harriet has been missing for more than forty years and is presumed murdered by her uncle Henrik (Christopher Plummer). Wanting to know the truth behind her disappearance, Henrik hires a disgraced journalist (Daniel Craig) to discover the truth. Daddario is best known for her role in Percy Jackson & the Olympians: The Lightning Thief in which she played the female lead.

For obvious reasons, the role of Harriet isn't that large, so I'm quite curious how they plan to utilize Daddario in the film. Will she only show up in the photographs from the day she went missing or will there be extended flashback sequences? Which ever way they decide to work it, with Fincher behind the camera and Oscar-winning writer Steven Zaillian behind the pen, it's hard not to have total faith in their production.
