For “Spirit,” Miller’s adaptation of the classic Eisner film noir comic strip series, Johansson is in final negotiations to play a dangerous beauty named Silk N. Floss. Eisner’s strip was known for its women with dangerous curves, and Miller is intent on keeping that tradition. Floss is a sexy and intelligent secretary with a vindictive instinct that makes her the perfect accomplice to the Octopus (Samuel L. Jackson), an evil mastermind.
This news is a bit odd, because Miller said he was adapting the Sand Saref storyline to be used in the film. From the review I wrote here, neither the Octopus, nor Silk N. Floss appear in the story. Will have to investigate further.
