The moment Boston Blue was greenlit, fans hoped Blue Bloods stars would be crossing over and reuniting with Donnie Wahlberg's Danny Reagan - but he played coy about how the other Reagans would be featured. "Now, it's just Danny going to this new world, but I can't say a lot about it - but I could say, if he's a Reagan, it will never be just Danny," Wahlberg told Fox News Digital in June. "There'll always be a Reagan a phone call away." Blue Bloods ran for 14 seasons on CBS, ending in December 2024.
