At its core, CBS’s cop drama Blue Bloods centers around the Reagan family, with five actors appearing in every episode, representing the principal adult Reagans, each involved in New York City law enforcement. However, the show’s exploration of its characters’ personal lives alongside their professional ones necessitates a diverse cast of supporting actors and guest stars.
This expansive approach to storytelling allows Blue Bloods to feature contributors from various backgrounds, including a notable number of Broadway actors that many viewers may not be aware of. Additionally, the series has welcomed several well-known celebrities over its long run. Here are five of the most prominent actors who have made significant contributions to Blue Bloods through their guest star roles.
Dylan Walsh as NYC’s Narcissistic Mayor
Dylan Walsh is perhaps best known for his role as Dr. Sean McNamara in all 100 episodes of FX’s acclaimed drama Nip/Tuck. He also appeared in the 1995 adaptation of Michael Crichton’s novel Congo and became a recurring cast member on Superman & Lois in 2021.
In Blue Bloods, Walsh began portraying New York City Mayor Peter Chase in Season 10, making sporadic appearances since then. When viewers first meet him in Season 10, Episode 8, he positions himself as an ally to Erin Reagan (Bridget Moynahan), promising to endorse her campaign for District Attorney. However, Erin soon discovers that he has made the same offer to her rival, revealing his true colors as an opportunist more interested in exerting influence than supporting the best candidate. Throughout his 12 appearances, Mayor Chase proves to be a challenging figure for the Reagan family, necessitating negotiation and strategy in their dealings with him.
