It’s time to gather around for dinner in the Reagan household with beloved Blue Bloods characters.

The CBS series, which premiered in 2010, is a police procedural following the Reagan family. Helmed by patriarch Frank Reagan (Tom Selleck), New York City’s police commissioner, the entire family are involved with law enforcement.

Frank’s oldest son, Danny (Donnie Wahlberg), is an NYPD detective; his younger son, Jamie (Will Estes), is an NYPD sergeant. His daughter, Erin (Bridget Moynahan), is the trial bureau chief of the New York County District Attorney’s office. Frank, his children and his father, retired commissioner Henry Reagan (Len Cariou), work tirelessly to keep N.Y.C. safe.

But in a city as large as the Big Apple, crime families, corrupt cops, drug cartels and more constantly hinder the NYPD and the family’s efforts, often forcing them to ask how far they’ll go to achieve justice. Over 13 seasons, Blue Bloods has aired 275 episodes (and counting), and on February 16, the show returns with season 14, which was green-lit after the entire cast and crew reportedly agreed to a 25% pay cut to enable production.

With the new season’s arrival, here’s everything to know about the cast and characters of Blue Bloods.Tom Selleck plays Frank Reagan, the N.Y.C. police commissioner. In addition to his three children involved in law enforcement, Frank had another son, Joe, who died in the line of duty.

Selleck doesn’t just play the patriarch of the series — the actor himself is considered a role model by the rest of the cast. In 2021, his costar, Will Estes, told Looper that Selleck was an exemplary co-worker.

“You come on set, and you know you’re working with somebody who’s very well studied and very professional and executes time and time again, every scene,” he said. “You need to be on your toes when you work with him, which makes it a lot of fun.”

Before joining Blue Bloods, Selleck was best known for his leading role as Thomas Magnum in Magnum, P.I. The series ran for eight seasons between 1980 and 1988, and Selleck was awarded a Primetime Emmy in 1984 and a Golden Globe in 1985 for his performance.

Selleck has had major film roles as well, most notably in the hit comedy Three Men and a Baby (1987) and the rom-com In & Out (1997). The latter film was especially notable for portraying a same-sex relationship in a mainstream comedy.

In his personal life, Selleck married his first wife, model Jacqueline Ray, in 1971, after which he formally adopted Kevin Shepard, Ray’s son from a previous relationship. The couple divorced in 1982. Five years later, Selleck married Jillie Mack, an actress he met after seeing her in the musical Cats. 1988, they had their daughter, Hannah Selleck, who is now a professional equestrian.
