Overview
- Andrew Terraciano said he learned he was being replaced as Sean Reagan on his college graduation day, followed by a supportive call from Donnie Wahlberg.
- He has not watched Boston Blue yet because he is pursuing a master’s degree, though he plans to and says he would return if Wahlberg asked.
- Mika Amonsen now plays Sean in the CBS spinoff, which premiered on October 17 and has been renewed for a second season.
- Co‑showrunner Brandon Margolis said the recast reflected a new creative direction and energy for the character and for Danny Reagan as a father to a young cop.
- Amonsen said he felt pressure to honor Terraciano’s portrayal, kept certain stylistic choices, and has seen both negative reactions and viewers embracing his take.
