“Blue Bloods” typically follows varying members of the Reagan family as they engage in law enforcement-related activities like general policing, detective work, and litigation. Due to the show taking place in New York City, there is often tons of room for guest actors and background characters, including those who appeared in its creator’s other series. One such example is Derek Hedlund, who played Special Agent JT on “FBI” — and likewise played multiple characters on “Blue Bloods.” But before we dive in a little further, it’s important to take note of the circumstances that allowed Hedlund to pull off such a feat.
The series “FBI” is created by Dick Wolf, who has been responsible for franchises like “Law & Order” and “One Chicago,” as well as “FBI” and its spin-off shows. In an interview with Variety, Wolf spoke about what it was like to be in charge of such an empire, and he said, “There are 56 actors under contract. The concept is there are nine shows, and anybody who’s in any of the nine shows can appear in the other eight, even on different networks. It’s pretty cool.”
However, it seems as if Wolf didn’t anticipate one of the early main actors from “FBI” to appear as several different characters in “Blue Bloods,” as Hedlund did.
