What keeps Chicago P.D. so authentic after more than a decade? It’s not just the writing or the direction — it’s the bond between the cast members who bring these characters to life.
Behind the camera, the team feels like a real family. Marina Squerciati (Kim Burgess) has often shared that the trust among castmates helps them tackle emotionally demanding scenes. Patrick John Flueger (Adam Ruzek) agrees, saying that after so many years together, “we’ve become a family, on and off set.”
That closeness shines through in every episode. You can feel it in the way Burgess and Ruzek argue but still care deeply for each other, or how Voight guides his team with a mix of discipline and compassion. The emotional truth in these relationships gives the show its unique power.
Fans also love seeing snippets of that real-life friendship online — playful behind-the-scenes photos, heartfelt birthday posts, and candid interviews showing how much the cast genuinely enjoys working together.
This camaraderie fuels the show’s authenticity. Viewers aren’t just watching characters; they’re witnessing connections built over years of shared experience. In an era where many long-running series lose their spark, Chicago P.D. keeps its heart beating strong.
