Maggie Grace joins spy thriller

Tom Cruise, Cameron Diaz star in James Mangold film

Maggie Grace is in negotiations to join Tom Cruise and Cameron Diaz in Fox's untitled Wichita project, a spy thriller directed by James Mangold.

The project centers on a lonely woman (Diaz) whose seemingly harmless blind date suddenly turns her life upside-down when a super spy (Cruise) takes her on a violent worldwide journey to protect a powerful battery that holds the key to an infinite power source.

Grace is playing Diaz's sister, who is getting married, excited that Diaz will take the place of their late father and walk her down the aisle.

Mangold's partner Cathy Konrad is producing with Todd Garner, Steve Pink and Joe Roth.

Grace has been on fire since starring as Liam Neeson's daughter in "Taken," which has raked in more than $224 million worldwide.

She recently wrapped playing the female lead opposite Adrien Brody and Forest Whitaker in Sony's "The Experiment" and is shooting "Flying Lessons." The indie is being exec produced by Mark Johnson.

Grace, repped by ICM and 1 Management, will shoot the thriller in October in Boston.
