The Reagans are a tight-knit clan both on and offscreen. Leading up to the final episodes of CBS‘s family cop drama Blue Bloods, which kicks off this October with the second half of Season 14, we spoke to many of the long-running series’ cast members about their experiences on the action-packed drama. No surprise, they also had a lot to say about their beloved costar Tom Selleck, who plays New York City Police Commissioner Frank Reagan, Blue Bloods‘ patriarch.

Check out the below gallery to see the kind words the cast had for Selleck.

Donnie Wahlberg
“It can never be overstated how much he’s committed to the show. He stays behind and works on the show in post-production. He works on the scripts before they’re even brought to the cast. He is just really dedicated to the show and he treats it very seriously. He is to Blue Bloods as Frank Reagan is to the NYPD and to the Reagan family.”

Bridget Moynahan
“He shows up and gives a hundred percent—whether it’s to Donnie, or to me, or to that guest star who’s on for one or two scenes—there’s no difference. He’s always present and respectful and welcoming, so it’s been a pleasure.”

“Tom has always been on point in terms of the spirit of the show, the essence and the direction of it. I don’t think we’d still be here [without him].”
