Why Henry Reagan From Blue Bloods Looks So Familiar

For 11 years, fans have been tuning in week after week to catch up with the Reagan family. The Reagans are centered around Frank (Tom Selleck), whose position as NYPD commissioner often leads to conflict as his children, including Officer Jamie Reagan (Will Estes), Detective Danny Reagan (Donnie Wahlberg), and ADA Erin Reagan (Bridget Moynahan) attempt to navigate their careers within the criminal justice system as well. While Selleck may be one of the best-known actors in the show, "Blue Bloods" has an impressive cast, including Len Cariou, who stars as Reagan patriarch, Frank's father Henry.
