Paramount Pictures, once shaky about the prospects of the Marc Forster-directed zombie extravangza World War Z, is now on track to make the picture this summer. I'm told that Mireille Enos, star of the AMC hit series The Killing, is in talks to play Karin Lane, the wife of Gerard Lane, the character played by Brad Pitt in the adaptation of the Max Brooks book. In The Killing, she plays Sarah Linden, the homicide detective trying to solve the murder of Rosie Larsen. This will be the first major-studio starring role for Enos, who starred for three seasons on HBO's Big Love. She's repped by Innovative and Authentic.
