For the fifth annual ONE CHICAGO DAY, run by NBC out of the Lagunitas Brewery Tap Room, we got the opportunity to chat at length with some of the show’s creators, writers, and stars about all things ONE CHICAGO.  The crossover event that they have planned for this season airs tonight as a 3 hour movie (starting at 8/7c on NBC) with a nice day out at the Bears game. It quickly turns into something we haven’t seen before on the shows.  CHICAGO FIRE showrunner Derek Haas sat with us and discussed writing his 50th episode of TV, how the crossover idea came to be, and again, why Otis (spoilers) had to die.
