Final appearance of James Whitmore Jr. as Sgt. Bernie Terwilliger. However, he would go on to direct many episodes of the series.
First appearance of Charles Hallahan as Captain Devane. He will keep that role for the remainder of the series and eventually be included in the opening credits.
In this season, the opening credits now feature a different angle of McCall's car, shots of an old barrio, and a woman lying dead. The theme music has a noticeably different arrangement as well.
