Len Cariou to Reprise His ‘Blue Bloods’ Role in Spinoff Boston Blue

Len Cariou is set to reprise his beloved Blue Bloods role as Henry Reagan in the upcoming spinoff Boston Blue, bringing a familiar face—and a deep sense of legacy—to the new series. Cariou’s return reconnects fans with the Reagan family patriarch, whose wisdom and steady presence helped define the long-running CBS drama.

While Boston Blue shifts the focus away from New York and into a new city and cast of characters, Henry Reagan’s appearance serves as a bridge between the original series and its next chapter.
