Last week the upcoming NBC series Chicago Fire filmed an accident scene so realistic that Chicago authorities had to post signs around the location requesting people not call 911.
Thanks to one of our readers, Tracy, we have a few shots of the shoot which, as you can see, includes large pieces of debris falling onto two cars below.
Chicago Fire, which stars Jesse Spencer, Taylor Kinney, Monica Raymund, Lauren German and Eamonn Walker, will premiere on NBC on October 10.
The series will continue filming in Chicago through the end of the year. If you spot them filming around town, let us know about it at firstname.lastname@example.org!
