Boston Blue recast Andrew Terraciano as Sean, but could the Blue Bloods alum still make an appearance in the future?
During an exclusive interview with Us Weekly, Terraciano, 22, weighed in on a potential return despite Mika Amonsen currently playing Donnie Wahlberg‘s onscreen son, saying, “I said it to Donnie on the phone. If he says the word, I’ll be there. Not just with Blue Bloods or Boston Blue, but with anything in life.”
Executive producer Brandon Margolis opened up the chances of involving Terraciano in the spinoff — perhaps in a role that nods at his Blue Bloods origins.
“I love that idea. It’s really clever and I think it’s something Donnie would probably be into as well,” he teased to Us. “Because he’s the one always trying to work in New Kids on the Block references.”
He continued: “I’m sure Donnie would be open to it. But I think that it’s a very clever idea. If the right opportunities are there, we never say no to a great idea.”
Terraciano got his start on CBS’ Blue Bloods, appearing in nearly 300 episodes from 2010 to 2024. His role as Sean allowed him to share the screen with brother Tony Terraciano, who played Donnie’s eldest son, Jack Reagan. Despite becoming a beloved presence at the Reagan dinner table, the Blue Bloods spinoff, Boston Blue, premiered in October with Amonsen now starring as Sean.
“I definitely felt a ton of pressure at first. I felt the pressure to respect an actor before me because I wanted to respect Andrew the best I could,” Amonsen recalled. “There were even certain visual choices that I made that I wanted to keep in terms of hair styling and certain ways of being [as Sean].”
Amonsen wanted to pay tribute to Terraciano’s take on the character.
“I really want to maintain Sean as close as I can in the ways that I do it out of respect for this character that everyone loves — but also the character Andrew built,” he continued. “When I booked the show, it all happened really quickly. It was within about a week’s time and I was really thrown into it quickly. I did binge watch as much as I could and I found doing the later seasons was more helpful. I wanted to get a sense of who Sean was toward the end of the show. I really wanted to get a sense of his character at that point into adulthood and his relationship with Danny.”
After rewatching episodes of Boston Blue, Amonsen found ways to honor Terraciano.
“I wanted to respect Andrew’s portrayal of Sean as much as I could — but also adding something to my own version. The showrunners Brandon Sonnier and Brandon Margolis have been really good at giving me a lot of freedom to explore that new dynamic with Donnie,” he shared. “Watching Andrew’s performance, I actually noticed a lot of similarities just between us as people, and our energy. It’s quite upbeat. I have a lot more of an upbeat energy myself. So that was a bit comforting. I definitely kept that within myself and didn’t feel like I was obligated to change that part of me — which was nice — in terms of making it my own.”
Amonsen concluded: “We’re really just exploring what would have been. Of course, it is my own version of it but at the same time we haven’t seen this relationship with Sean and his dad before. He’s coming into this whole new position because from what I understand, the exploration of Sean being a cop wasn’t something that was on the table.”
Terraciano, meanwhile, expressed gratitude for his time on Blue Bloods.
“It’s beautiful because you’ll always remember every single line and every day that you had the opportunity to be that character,” he shared with Us earlier this month. “It doesn’t mean for even a second that somebody else can’t go and do something beautiful with it.”
Terraciano celebrated the CBS show, adding, “I got the joy of playing Sean, and I got to send him off into the world. Now somebody else gets that joy. We’re both getting to show what we do and then send Sean off into the world.”
Boston Blue airs on CBS Fridays at 10 p.m. ET.
