NBC’s #OneChicago Day is becoming an annual tradition, and for fans it’s as welcome a celebration as Christmas, Hanukkah, and Diwali all rolled into one. Since the Chicago casts did such a good job with their Twitter takeover last year, this year we turned over our account to P.D. star Marina Squerciati, Med star Nick Gehlfuss, and Justice star Joelle Carter — while P.D. co-star Sophia Bush snapped some pics for Yahoo TV’s Instagram account. As always, the Chicago group did not disappoint. Click through to see what it’s like to work with this good-looking gang of goofballs.
Chicago Fire airs Tuesdays at 9 p.m. ET on NBC. Chicago P.D. airs Wednesdays at 10 p.m. ET on NBC. Chicago Med airs Thursdays at 9 p.m. ET on NBC. Chicago Justice is coming to NBC in 2017. Watch clips and full episodes of the Chicago shows on Yahoo View.
