The cast that will portray President George W. Bush’s inner circle in Oliver Stone’s upcoming political biopic W is starting to come together. Elizabeth Banks (Definitely, Maybe) will join star Josh Brolin (pictured) as First Lady Laura Bush, James Cromwell is in negotiations to play George Bush Sr., and Jeffrey Wright (Casino Royale) is in talks for the role of Colin Powell. But at press time, it was still unclear who will take the role of Vice President Dick Cheney. A source close to the production tells EW that Stone will reach out to Oscar winner Robert Duvall, though the actor’s agency says that an offer has not yet been presented. W, which was penned by Stanley Weiser (who co-wrote Wall Street with Stone), aims to explain how Bush 43 went from being a hard-partying college student to the most powerful man in the world. Stone has said that he wants to make “a fair, true portrait of the man,” but controversy will likely dog the film, which is described in an internal positioning statement as follows: “W is the improbable story of a man who went to the White House despite getting fewer votes than his opponent; who became commander-in-chief despite having avoided military combat himself; and who became the least popular president ever elected to a second term. W will shock and surprise you and leave you questioning everything you believe to be true.” Filming is set to begin on April 21 in Shreveport, La. W is being produced by Moritz Borman (who worked with Stone on World Trade Center and Alexander) and Jon Kilik (Babel and Alexander). QED International is financing the film.
