EXCLUSIVE: Michael Mann is in talks to develop to direct The Big Stone Grid, a cop thriller that Sony Pictures bought as a spec script last year by S. Craig Zahler. Michael De Luca, who’s on the Oscar circuit for Moneyball, is producing ths one. The script is a hard-edged thriller in the vein of Seven and Marathon Man, about two decorated detectives who uncover a terrifying extortion ring that operates within the secret underbelly of New York City. The plan is for Mann to do a pass with the scribe, but don’t be surprised if he relocates the action to L.A., where he made such crime sagas as Heat and Collateral. Mann is likely to next direct Go Like Hell, the duel between Ford vs. Ferrari for sports car supremacy in the 60s that he is developing at Fox. He’s also exec producing the HBO series Luck with David Milch. That series, which was renewed for a second season, is building into quite an interesting look at the world of horse racing at Santa Anita. Mann is repped by CAA.
