Carey Mulligan was supposedly hand-picked to play Eliza Doolittle in the upcoming 'My Fair Lady' film adaptation, but there's been no news about that project for quite some time now. However, the Sun has just reported that the producer of the film, Cameron Mackintosh, wants to reunite with Anne Hathaway for the project,essentially meaning that Carey is no longer attached to the lead role in the project.
A source tells the Sun that Mackintosh feels that having Anne would be a huge deal after her starring roles in 'Dark Knight Rises' and 'Les Miserables', which he also produced, as well as her recent Oscar win. A source tells the Sun, "Cameron feels having Anne on board will help replicate the success of Les Mis. The cockney accent won’t be a problem. She’ll pick it up in no time.”
There are both Broadway and film versions in development right now, but Anne seems to be the top choice for the film version after she proved her musical skills on 'Les Miserables'. However, if this story is true, it is surely a blow to Carey Mulligan, who was reported as screenwriter Emma Thompson's first choice to star as Eliza Doolittle.
The film is actively shown as being 'in development', but it has yet to hire a director, although Joe Wright was rumored to direct at one point.
