Luis Guzmán originally had the role of Charlie Lincoln, but after the pilot was shot, he was replaced by Malik Yoba. NBC then asked that the producers re-shoot the scenes in which he appeared.
The script for the eighth installation, entitled "Every Picture Tells a Story" was written but never filmed, because of the cancellation. This would have been episode production number 108.
Mykelti Williamson appears in the pilot episode in a cameo role as Detective Bobby 'Fearless' Smith, a role he originated on the 2002-03 NBC-TV series Boomtown. Like Raines, Boomtown was created by Graham Yost, and was set in Los Angeles.
