CinemaBlend: While everyone speculates feverishly about who will play Lisbeth Salander in David Fincher's adaptation of The Girl with the Dragon Tattoo, I've been wondering about the side characters, the Erika Bergers and Henrik Vangers of the book. They don't necessarily have to be played by big stars, but the smaller characters provide a nice texture to the central story of journalist Mikael Blomkvist and his hacker pal Salander.
