New developments are fueling speculation that Tom Selleck could return as Frank Reagan. When Blue Bloods premiered in 2011, it stood out by focusing on a multigenerational family of public servants, anchored by Selleck’s commanding performance as the Reagan patriarch.
Nearly a year after the show wrapped in 2024, its legacy lives on through Boston Blue, the franchise’s first spinoff. The series follows Danny Reagan as he relocates to Boston after Sean’s near-death experience. So far, Erin is the only Reagan to appear on screen, but more family cameos are widely expected.
Buzz intensified after news broke that Selleck signed with United Talent Agency, switching from CAA while keeping his longtime legal and PR partners. Though agency changes are common, the move comes during a rare acting hiatus for Selleck — his first since Blue Bloods ended — hinting he may be preparing for a return.
At the same time, CBS has already renewed Boston Blue for a second season before its first even finished airing, a strong sign of confidence in the spinoff. The early renewal also creates more room for familiar faces to step in — and with the show already referencing Frank Reagan, a cameo from Selleck now feels more possible than ever.
