Keira Knighley Replacing Marion Cotillard In Cronenberg's Cosmopolis?

ThePlaylist says that Keira Knightley could possibly be taking over the female lead in David Cronenberg's Cosmopolis. Marion Cotillard originally was set to star but likely had to leave over her recent pregancy. It's not the first casting shake up on the film as Robert Pattinson took over for Colin Farrell who left to focus on Total Recall. Paul Giamatti has been in talks for a role in the film but nothing has been confirmed. The production starts shooting in May so an announcement should be made soon.

While I'm not a fan of Pattinson's work I'm curious to see anything made by Cronenberg. It would make sense to see Knighley join the production as the role would be the wife of Robert's character. The actors are similar in age and make more sense to be paired up. Keria recently worked with Cronenberg on the film A Dangerous Method and could have made an impression with the director. I'm curious if Knighley is still up for a role in The Dark Knight Rises.
