Donnie Wahlberg’s Boston Blue is returning for a second season. So, after a major cast change, who’s coming back and who’s not?
Before Boston Blue, Blue Bloods followed the lives of the Reagan family, many of whom worked for the New York City Police Department under the guidance of New York City Police Commissioner Frank Reagan (Tom Selleck). Frank’s father, Henry Regan (Len Cariou), was also a central character on the show, along with Frank’s children, daughter Erin Regan (Bridget Moynahan), and sons Danny (Wahlberg) and Jamie Regan (Will Estes).
The show aired from 2010 to 2024 until CBS announced a spinoff. Wahlberg’s character will be at the center of the spinoff, which will get even more exciting as the former NYPD officer takes on a role with the Boston Police Department. He then teams up with Detective Lena (Sonequa Martin-Green), the eldest daughter of a prominent law enforcement family.
Despite keeping many details the same, Boston Blue underwent a change when Mika Ammonsen was added to the cast as Sean, who was conceived by Andrew Terraciano. Boston Blue was successful and broke the CBS record by breaking it.
