Jennifer Lopez was originally only producing, without an on-screen role. NBC asked her to star when she brought the series to them.
Jennifer Lopez performed the majority of her own stunts.
Even though the network wanted to order a larger amount of episodes, the show had only 13-episode seasons. Jennifer Lopez's schedule prevented her from doing more.
Production on the first season of Shades of Blue ran from June 2015 to November 2015.
