The whole history of how The Blues Brothers came to be is fascinating to me. Apparently, prior to that movie, there had been an informal ban on movie productions filming in (downtown) Chicago for decades under the Richard J. Daley administration, due to Daley hating a film produced there in the ‘50s that portrayed Chicago as a hive of mob activity. But by 1979, Daley was gone (“No, sir, Mayor Daley no longer dines here…he’s dead, sir.”) and The Blues Brothers was able to actually film on location with the cooperation of then-Mayor Jane Byrne, along with a few favors called in to Cook County Board of Commissioners President George Dunne, who was the father of Murphy Dunne (aka Murph of Murph & the Magic Tones).
