Former Married... with Children star Ed O'Neill will headline a new CBS cop drama produced by David Milch (NYPD Blue) and Anthony Yerkovich, Variety reports. O'Neill will play a tough Irish police detective with the NYPD in the tentatively titled Big Apple, which explores the "interconnected workings of the NYPD, the FBI and the mob." The network has committed to 13 episodes of the series and is hoping to have it ready for a midseason debut.
