Blue Bloods spin-off Boston Blue has cast two new actors joining Donnie Wahlberg
The cast of the Blue Bloods spin-off Boston Blue, led by Donnie Wahlberg, is slowly but surely getting built.
Though Tom Selleck, who starred as the Reagan family patriarch, isn’t expected to return as Frank Regan, his successor has just been cast.

The new show, which will air during Blue Bloods‘ Friday 10pm slot on CBS, will follow Danny Reagan taking a position with the Boston PD, as well as the Silver family, prominent among the Boston law enforcement, and helmed by patriarch Reverend Peters.
Over the weekend, Deadline confirmed that Reverend Peters, the Silver family patriarch, will be played by Ernie Hudson. He is best known for his work in the Ghostbusters franchise as well as Quantum Leap, Carl Weber’s The Family Business, and Miss Congeniality.
His character is “a renowned pastor of an historic Baptist church in Boston” described as an “open-minded, welcoming man that is comfortable in all traditions.”

He is the father of Mae Silver, Boston’s District Attorney, and grandfather to Superintendent Ashley Silver, rookie patrol cop Isaac Silver, and Detective Lena Silver.
Of those, the only other actor cast so far in the series, which will premiere this fall, is Sonequa Martin-Green, who will star as Lena.
