Maggie Grace, who starred in ABC’s Lost and the recent box office smash Taken, is in talks to join Tom Cruise and Cameron Diaz in their untitled spy thriller project for Fox, according to the Hollywood Reporter. As has been previously reported, the film finds Diaz as a lonely woman who goes on a blind date with a spy (Cruise) who takes her on a whirlwind worldwide mission to protect an infinite power source. If the deal goes through, Grace would play Diaz’s about-to-be-married sister. The project is set to shoot in Boston in October.
