The 13-episode series follows the detectives who keep their city safe, but are also corrupt. Lopez is producing alongside Ryan Seacrest, among others, while Barry Levinson is directing. Check out the promo in which Lopez and the cast talk about the shades of grey (and blue, duh) between right and wrong when it comes to crime. “Shades of Blue” does not yet have a premiere date.
