British actress Sienna Miller will replace Emma Stone as singer Sally Bowles for the final six weeks of the Broadway run of the musical “Cabaret.” The actress will join the cast of the musical – set during the rise of Nazism in Germany – on Feb 17. “Miller will take over from Stone, whose last performance is on Feb. 15, until the end of the show’s limited engagement on March 29,” the Roundabout Theatre Company said in a statement. Miller, who stars opposite Bradley Cooper in the Clint Eastwood directed film “American Sniper” about a Navy SEAL sharpshooter, made her Broadway debut in 2009 in “After Miss Julie.”
