In an interview with the Post-Gazette, Jason Beghe discussed how working on Chicago PD changed his perception of cops. Beghe noted that he never viewed cops as more than their jobs, but his work on the show had changed that, making him aware of the inner workings and full-fledged individuals they were and that their job was just a part of who they were . He added that he now sees cops as full individuals and not just cops, and that his thinking has changed in that way because of his work on the show.
“Honestly, after all this time, it’s becoming like a close personal relationship,” Beghe continued in reference to his Hank Voight character. “And like any good close relationship, I’m sure we learn from each other and influence each other.” The actor joked that some of Voight’s more violent tendencies passed over to him, and said his personal body count has gone up since he had taken on the role and he reacted more violently to cashier errors. But then he added that Voight taught him a few things and influenced him in some ways as he was sure he had to do the same for Voight.
