The Chicago Med Star Who Has Appeared In The Most Chicago Fire Episodes
Police procedurals and medical dramas have been milking the power of spinoffs and crossovers for decades. When it comes to creators who understand how successful shared universes can be on the small screen, look no further than Dick Wolf. Back in 1990, he launched a television juggernaut with "Law & Order," a series that has since produced several successful spinoffs. But in recent years, Wolf — in collaboration with Derek Haas and Michael Brandt — has turned his attention to the "One Chicago" franchise, an all-encompassing beast that delves into the worlds of heroic doctors, firefighters, and police officers working in the Windy City.
"Chicago Fire," "Chicago Med," "Chicago P.D.", and the short-lived "Chicago Justice" are the shows that make up the "One Chicago" franchise in its current iteration. While each show boasts a strong individual identity, the creators have embraced their crossover potential on multiple occasions. For example, some "Chicago Fire" stars have appeared in multiple episodes of "Chicago Med" throughout the years, and vice versa. But which actor from the medical drama has featured in most episodes of the firefighting saga?
Nick Gehlfuss has appeared in the most Chicago Fire episodes
As IMDb points out, Nick Gehlfuss, who plays an attending physician known as Dr. Will Halstead in the "One Chicago" franchise, is the "Chicago Med" actor who appears in the most episodes of "Chicago Fire," credited as starring in 20 of them at the time of this writing. Halstead goes through quite a lot over the seasons, with the character recently losing his job after taking the blame for a coworker's crime. Yaya DaCosta, who portrays April Sexton in the saga, comes in second, with 12 guest starring roles in the firefighting drama (per IMDb).
Gehlfuss' character joined the "One Chicago" franchise in 2015 and has remained a regular fixture since then. His first appearance in "Chicago Fire" comes courtesy of the Season 3 episode entitled "I Am the Apocalypse," which is the backdoor pilot for the "Chicago Med" spinoff. As of right now, his latest outing occurs in Season 9's "A Couple Hundred Degrees." Elsewhere, the "Chicago Med" alumnus also lent his talents to "Chicago P.D." throughout the years, showing up in 17 episodes of the cop drama between 2015 and 2020.
