Which one do you think fits the bill better?
My husband, who is a completist, purchased the extended Swedish version. Originally called Millennium, it actually ran on Swedish TV before it had a theatrical release. It's nine hours long. Therefore I'm more partial to Noomi Rapace because I've been exposed to her more than Rooney Mara.
Noomi just seems a little tougher, a little more grownup. It's more believable that the men she meets, Armansky and Blomkvist, fall for her just a little. Rooney just seems a little young, a little frail, although Lisbeth is frequently mistaken for a rebellious teen.
My husband, the completist, has also purchased all three books, The Girl with the Dragon Tattoo, The Girl Who Played with Fire, and The Girl Who Kicked the Hornet's Nest in hardcover. That will have to round out his purchases because Stieg Larsson died of a heart attack in 2004 at the age of 50.
