The show has also become famous for its many crossover storylines. There have been tie-ins with several of Dick Wolf’s further Chicago spin-offs including Chicago Justice, Chicago P.D. and Chicago Med. And there have also been several crossovers with Wolf’s other major franchise, Law and Order, specifically its Special Victims Unit show.
The show’s leads include Jesse Spencer as Captain Matthew Casey, Taylor Kinney as Lieutenant Kelly Severide and Lauren German as Paramedic Leslie Elizabeth Shay. Other major players include Monica Raymund, Charlie Barnett, David Eigenberg, Teri Reeves and Eamonn Walker. The main cast is completed by Yuri Sardarov, Christian Stolte, Joe Minoso, Kara Killmer, Dora Madison Burge, Steven R. McQueen and Miranda Rae Mayo.
Chicago Fire also had an expansive wider cast, too, including DuShon Monique Brown as Boden’s no-nonsense secretary Connie. Sadly, in March 2018 news emerged that the actress had died aged just 49. Wolf told TV network channel E! News in a statement, “The Chicago Fire family is devastated to lose one of its own. Our thoughts and prayers are with DuShon’s family and we will all miss her.”
