Charlize Theron, Colin Farrell, Ralph Fiennes and Willem Dafoe are attached to topline the Iraq-set action drama “The Hurt Locker”. Kathryn Bigelow is directing from a screenplay she co-wrote with war reporter Mark Boal, who recently co-wrote the story for Paul Haggis’ “In The Valley Of Elah,” starring Theron. “Hurt Locker,” follows the exploits of an elite bomb disposal unit. Forced to play a dangerous game of cat-and-mouse in the chaos of war, an elite Army bomb squad unit must come together in a city where everyone is a potential enemy and every object could be a deadly bomb. Principal photography is scheduled for later this spring. Farrell and Fiennes are co-staring in Martin McDonagh’s “In Bruges,” currently filming in Belgium.
