It looks as if David Cronenberg's film adaptation of Don DeLillo's novel Cosmopolis is becoming somewhat of a revolving door.  A few weeks ago we reported that Robert Pattinson had signed on to star in the film, bringing to an untimely end Cosmopolis' Colin Farrell-era.  Fast-forward to today and we're hearing reports that Keira Knightley may be taking on the film's female lead, replacing Marion Cotillard in the process.Kudos to The Playlist for connecting the dots provided by the Cosmopolis fansite which points out that the film's production company (Alfama Films) now lists Knightley as starring in the project.  Knightley recently worked with Cronenberg on A Dangerous Method so perhaps the two developed a rapport that would make this potential move a little less "from left-field."  Of course, we'll bring you confirmation on the matter as soon as we have it.  Cosmopolis is currently scheduled to begin shooting in Toronto around mid-May.  For more, hit the jump to check out a synopsis of DeLillo's novel.Here’s a plot summary for Delillo’s Cosmopolis [from Wikipedia]:

Cosmopolis is the story of Eric Packer, a 28 year old multi-billionaire asset manager who makes an odyssey across midtown Manhattan in order to get a haircut. The stretch limo which adorns the cover of the book is richly described as highly technical and very luxurious, filled with television screens and computer monitors, bulletproofed and floored with Carrara marble. It is also cork lined to eliminate (though unsuccessfully, Packer notes) the intrusion of street noise.

Like James Joyce’s Ulysses, Cosmopolis covers roughly one day of time and includes highly sexed women and the theme of father-son separation. Packer’s voyage is obstructed by various traffic jams caused by a presidential visit to the city, a funeral procession for a Sufi rap star and a full-fledged riot. Along the way, the hero has several chance meetings with his wife, seeing her in a taxi, a bookstore, and lying naked in the street, taking part in a movie as an extra. Meanwhile, Packer is stalked by two men, a comical “pastry assassin” and an unstable “credible threat”.

Through the course of the day, the protagonist loses incredible amounts of money for his clients by betting against the rise of the yen, a loss that parallels his own fall. Packer seems to relish being unburdened by the loss of so much money, even stopping to make sure he loses his wife’s fortune as well, to ensure his ruin is inevitable.
