Dick Wolf's trio of Chicago shows, which actually shoots in the Windy City, is one of the biggest franchises on primetime TV, with multiple characters overlapping and interacting with each other across three different shows: Chicago Fire, Chicago P.D. and Chicago Med. And with the possible addition of Chicago Law (working title), the Wolf's Pack is about to get a whole lot bigger. But despite the high drama, the actors and actresses know how to goof off when the cameras aren't rolling. Check out some candid behind the scenes photos, plus a few on-set shots.
