The story follows two friends, who are also San Francisco cops, whose fathers were once partners on the police force. The older generation is forced out of retirement to help their sons crack a case, with typically antagonistic results. The actioner is meant to have an updated "Lethal Weapon" flavor that plays into edgier R-rated territory. Turner and producer Andrew Panay ("Wedding Crashers") first developed the pitch, then called "Blowback," five years ago with Dwayne Johnson, then known as The Rock, attached to one of the roles. The current iteration is not yet set up at a studio. Reynolds returns to theaters next month in the indie thriller "Buried," and will illuminate screens next June in "Green Lantern." Cooper ("The Hangover") hits theaters in January with the thriller "The Dark Fields." A sequel to "The Hangover" is being lined up for a May release.
