Trivia
Weapons Manuals
When she is at her beauty salon, Jake's Ex-fiance (Carrie Fisher) has two weapon manuals on her desk: "M79 Flame-Thrower" and "Anti-Personnel Mines". It's difficult to see the other text on the manuals, but from the logos, it looks like Government files. I wonder how she got those...
Use of Unnecessary Violence
This humourous line proved very controversial within the Chicago Police Department. Due to this line, the Chicago Police Department banned use of its name and insignia in films and television shows until the 2000s. Several movies, such as The Negotiator, used names like "Metro Police" because the name "Chicago Police" could not be used.
Police Car Wreckage
About 60 police cars were used in the film. Most of these cars were humorously wrecked throughout the film. Here are some shots of it.
Overreaction
The Blues Brothers are two petty criminals who are guilty of merely reckless driving, speeding, running red lights, and other traffic violations. Yet, in order to arrest them, they need the Illinois State Police, the Chicago Police, the Chicago Fire Department, the Chicago Police SWAT team, and the United States Army. Kind of an overreaction, wouldn't you say?
