Blue Bloods is one of the most enduring and beloved police procedurals on television. The series is the second-longest running show on CBS today, next only to NCIS, and is in production for its 14th and final season. As the series comes closer to its finale, credit must be given to the reasons why the show became, and remained, as successful as it is. Unlike other prominent cop shows, the series doesn’t follow a specific precinct or squad. Instead, the show is centered around the Reagans, a prominent family with legacy and importance in New York City law enforcement. Its members have roles that range from detective to district attorney — even all the way up to the commissioner of the NYPD! Even among the most popular law procedurals on television, Blue Bloods has such a distinct vibe and lasting power that makes it feel more timeless than other series. Of course, much of that credit goes to the fantastic ensemble cast and memorable writing of the show, but there’s one foundational character that cements Blue Bloods as television royalty: Tom Selleck and his portrayal of Commissioner Frank Reagan.
Selleck Is the Father of the NYPD’s First Family
The crux of Blue Bloods is that it follows a family of people working in law enforcement. Not a found family or friends-turned-family — an actual blood-related family that grew up together and are still tightly connected. That’s what separates the series from other prominent procedurals. The Reagans are the titular “blue bloods” of New York Law enforcement, who are known throughout their fields as people that excel in their careers. Selleck’s character, Frank, is the literal and spiritual patriarch of this prestigious and recognizable family. He sits at the head of the table for both the NYPD, as commissioner, and of his family, at their weekly dinners. In this unique role, Frank serves as the foundation for the family dynamics that separate the show from other series. In addition to the classic police drama that ensues in the show, there are also intimate family dynamics at play, and it often falls to Frank to be the leader, mediator, and role model for the rest of his family.
One of the ways that the show emphasizes the importance of its family dynamics is through the weekly dinner scenes that appear in every episode. Affirming how tight-knit the Reagan’s are, they meet once a week on Sunday for dinner in a scene that allows every character to interact with one another, serving as the setting for some of the show’s most emotionally intimate and important scenes. Frank, as the head of the family and table, is an irreplaceable part of these dinners and dynamic. It’s him who steps in to quell conflict between the siblings. It’s him who gives the most advice to the other characters about their personal and professional struggles. It’s him who leads the family by example and is the reason they are so renowned in New York. Because of his importance to every other character, and his constant role as the backbone of the family, Frank is established as the most integral character of the series.
Tom Selleck Plays a Unique Role Among Police Characters
Frank plays one of the most unique and multifaceted roles of any character in a law procedural. In addition to being the head of his family, Frank is the commissioner of the NYPD — one of the most iconic, recognizable, and controversial police departments in the entire world. As with any cop show, the series portrays characters that are the ideal versions of law enforcement and doesn’t often criticize the police with intense scrutiny; copaganda is an inherent part of the premise. Blue Bloods ultimately has to make a series about a family of cops endearing to the public, and a major part of that success is because of the standard set by Frank and his position. In the show’s world, it’s far easier to believe in the ideal version of police officers if people like Frank and his family serve in the capacities that they do. Frank is at the top of the ladder and his positive influence on the force feels palpable because of how we see him lead his own family.
Tom Selleck Was Destined for This Role

In the same way that Blue Bloods wouldn’t be the same without Frank, Frank could not be portrayed by anyone other than the incomparable Tom Selleck. Tom Selleck was a gentleman’s 65 years old when Blue Bloods first premiered in 2010, but his age actually landed him in the perfect sweet spot to be the head of an extended family. Selleck was already well-recognized for his action-packed performance in Magnum, P.I., one of the best TV action series in the 1980s. Moving up from a hot shot private investigator to the commissioner of the NYPD is the picture-perfect definition of “aging gracefully.”
