Carey Mulligan, Britain’s next great export, who can be seen in the upcoming Sundance smash An Education (Oct. 9) has just been cast as Michael Douglas’s daughter in Oliver Stone’s Wall Street 2: Money Never Sleeps for Twentieth Century Fox. The 24-year old, who played one of Keira Knightley’s little sisters in 2005′s Pride & Prejudice, and will star opposite her again in Fox Searchlight’s Never Let Me Go, will co-star as the estranged daughter to disgraced corporate titan Gordon Gekko. Her character will also be romantically linked to Shia LaBeouf’s eager Wall Street trader in the film. Scribe Alan Loeb penned the latest draft of this drama that also has Josh Brolin and Frank Langella in talks for various parts. Filming is set to begin this fall in New York.
