Dermot Mulroney’s casting in Chicago Fire appears to redeem a role he played five years ago. Chicago Fire has had a famously long run, airing over 250 episodes, and is a part of the One Chicago universe, which features several different shows that all tie together. Over the years, Chicago Fire’s cast has primarily remained the same, with a few occasional changes. However, the next season will change the show in a big way. Season 13 of Chicago Fire marks the dawn of a new Firehouse 51 Chief, as Dermot Mulroney has been cast as Chief Boden’s replacement.
Eammon Walker, who plays Chief Boden, was the first actor-producer Dick Wolf cast when introducing the fire department in his One Chicago franchise. Starring in Chicago Fire since its pilot episode in 2012, Boden has been around this universe for quite a while. Therefore, when Boden exited his role as Chief in season 12’s finale, becoming First Deputy Fire Commissioner, fans were naturally left shocked. However, despite the former chief selecting a successor, Christopher Hermann will not be Boden’s replacement in season 13, due to Hermann’s rank. Instead, the role will go to a new character called Dom Pascal, played by Dermot Mulroney.
