Get ready for a shake-up at Firehouse 51! Dermot Mulroney is set to join the cast of "Chicago Fire" as the new fire chief, Dom Pascal, in the show's upcoming 13th season. This casting change comes after Eamonn Walker's departure from the role of Battalion Chief Wallace Boden, who exited as a series regular at the end of season 12.

While specifics about Pascal's character remain under wraps, sources close to the show have shared some intriguing details.

Chief Pascal is described as a cheerful individual who began his career with the Chicago Fire Department before spending the past decade working in Miami, Florida. His leadership style is expected to differ from that of his predecessor, Boden, offering a fresh dynamic to the team at Firehouse 51.

Dermot Mulroney, known for his roles in various films and TV shows, will be bringing his talents to the popular firefighting drama.

His arrival marks a significant shift in the series, particularly after the transition period following the end of Boden’s tenure.

The announcement might come as a surprise to some fans, especially since there were expectations for veteran firefighter Christopher Herrmann (played by David Eigenberg) to step into the chief role after Boden’s promotion.
