Nicole Kidman is set to challenge her MISSION: IMPOSSIBLE-starring ex-husband Tom Cruise on the big screen after signing on to play an action woman in a new espionage thriller. The actress will also produce the untitled project, which is described by insiders as a female-led The Bourne Identity. MR + MRS SMITH screenwriter Simon Kinberg is reportedly writing the script for the film. Ironically, Kidman was originally attached to star alongside Brad Pitt in Mr + Mrs Smith, but dropped out to allow Angelina Jolie to take her place.
