Exploring the Evolution of Sean Reagan in Boston Blue: Mika Amonsen's Take on the Character
Mika Amonsen, who stars in the Blue Bloods spinoff Boston Blue, has faced some backlash from fans after taking over the role of Sean Reagan from Andrew Terraciano. Despite the negativity, Amonsen is grateful for the fans who appreciate his portrayal of the character and are enjoying the show's direction with Sean.
Sean Reagan was originally introduced on Blue Bloods, a series that followed the Reagan family's lives. After the show ended in 2024, CBS announced the spinoff Boston Blue, with Amonsen joining the cast as Sean. Amonsen felt pressure to respect Terraciano's portrayal of the character and made visual choices to maintain continuity.
Amonsen binge-watched episodes of Blue Bloods to understand Sean's character development and relationship with his father, Danny. He aimed to honor Terraciano's performance while adding his own touch to the character. Showrunners Brandon Sonnier and Brandon Margolis gave Amonsen the freedom to explore the new dynamic with Donnie Wahlberg's character.
Amonsen found similarities between himself and Terraciano in terms of energy and upbeat nature, which he incorporated into his portrayal of Sean. He emphasized that while it is his version of the character, they are exploring new aspects of Sean's relationship with his father that were not previously explored on the show.
Boston Blue airs on CBS on Fridays at 10 p.m. ET. Amonsen is dedicated to honoring the character of Sean while bringing his own interpretation to the role, creating a new dynamic for fans to enjoy.
