"It's a pretty big [One Chicago] family," series creator Dick Wolf said in 2019. "Everybody gets along. I mean, there are no squeaky wheels in the cast... I've never had anything like it, which is, I think, only visible to the audience by the fact of how good they are together. There are no line counters. There are no 'Where's my close-up?' It's a remarkably ensemble-like world."
