Actress Emma Stone is in talks to become the next big Hollywood star to hit the stage as Sally Bowles in hit Broadway musical Cabaret. Sources tell The Hollywood Reporter that The Amazing Spider-Man star is the front-runner to replace Michelle Williams when she steps down as Bowles. The Brokeback Mountain star made her Broadway debut in the Roundabout Theatre Company's production, which also features Alan Cumming. Williams has extended her run through 9 November (14). Jane Horrocks and Natasha Richardson have also played Bowles in directors Sam Mendes and Rob Marshall's revival of the 1966 Cander and Ebb musical.
