Audio problem: In the scene at the Palace Hotel Ballroom, when the Blues Brothers are singing their 2nd tune (Sweet Home Chicago), you can hear both Jake and Elwood on the soundtrack but Elwood is dancing down the middle aisle without even a microphone in his hand and his mouth is not moving. There is also a shot during the same song where Jake's singing and pauses do not line up with what we see visually. When he sings "baby don'cha you want to go-oh - -" we see his mouth stop moving, then when he pauses, his mouth is still singing. As a matter of fact, the entire number has mistakes like this and mistakes of continuity. (01:54:20)
Continuity mistake: Near the end of the movie when the brothers are preforming "Sweet Home Chicago", they do a lot of spins and turns. The very last spin they do puts Jake towards the audience and Elwood towards the band. Then the camera angle is changed and Elwood is towards the audience and Jake is towards the band. (01:55:05)
Continuity mistake: When Carrie Fisher is shooting at Jake and Elwood in the tunnel under the Palace Hotel, she hits a water pipe and water sprays everywhere in a mist. In the next shot of Jake and Elwood lying in the mud, there's no spray visible behind them at all. When Jake stands up a few seconds later, the spray is back, but is more directed now. (01:57:39)
Continuity mistake: When we see the Nazis falling in their car, one shot shows the car from above falling into an area without any buildings around the docks. When the car lands however it is in a built-up area of the city. [Due to the lack of available special effects, the crew had to actually drop a car from a helicopter onto the area shown without any buildings because of safety issues. The landing of the car in the city area was edited into the scene, the rest of it was real.] (02:05:45)
Visible crew/equipment: When they're driving on Lower Wacker Drive in the end, you can see the shadow of the camera. The camera is on the hood of the car. It's visible in the scene where they almost hit a cyclist. (02:08:05)
Revealing mistake: In the last scene where we see multiple police cars pile up under the L-platform, at one point you can see the boards that allow some of the cars to drive on top of the lower cars. (02:08:30)
Continuity mistake: When Carrie Fisher confronts Jake in the underground tunnel, Jake can be seen wearing a pair of black wellies instead of his usual shoes. (02:10:00)
Revealing mistake: During the last chase scene, pursued by the Nazis, the Bluesmobile stops short of running off of the bridge. You can see the steel guide rails behind the front wheels which will help the car get its front wheels back on the bridge when he slams it into reverse. (02:10:45)
Revealing mistake: When Elwood drives the Blues Mobile backwards from the half-finished bridge, just as it flips you see something on the underside of the car on the far right. It's either a coiled spring or a tube with an explosive charge used to flip the car over. (02:10:50)
Continuity mistake: When the Blues Brothers escape from the road construction at the bridge and the Illinois Nazis, Elwood flips their car so it lands behind the Nazi leader's. When the car starts to flip, though, it does so while driving backwards, so it should land with its backside first and Elwood would have to reverse in order to drive back, but it comes down with its front first. Also, as it shoots over the Nazi car, it comes driving off a ramp, and not crashing down at the end of a somersault. (02:10:50)
Factual error: When the Blues Brothers are trying to escape the Illinois Nazis, they are on a freeway heading through a construction site. They break through several barricades, jam on the brakes, and stop just before they go off of a bridge. They slam the car into reverse and flip through the air to escape. The Illinois Nazis go over the bridge. The bridge is in Milwaukee, WI. The tall white building in the background is the US Bank building in downtown Milwaukee, WI. As the Nazis fall to earth, they fall past a building in downtown Chicago, IL before going through the street on impact. The Nazis fell from Milwaukee, WI to Chicago, IL. (02:11:00)
Continuity mistake: At the end of the movie, just before crashing through the Daley Building, the driver's side rear window is rolled down, then it is up again just before (and as) the car falls apart. (02:11:50)
Continuity mistake: As the Bluesmobile screeches to a halt on the sidewalk at the end of the long chase, it leaves obvious tire trails on the sidewalk. But in the very next shot (when the car breaks apart), the trails are gone. (02:12:00)
Continuity mistake: When the multitude of police are shooting through the door at the end of the film, there are loads of bullets shot at the door, then there are only a couple dozen bullet holes then there is a bunch of bullet holes. (02:12:40)
Audio problem: Near the end, when the officers are getting out of the van, they are shouting "Hut! Hut! Hut!" but their lips aren't moving. (02:13:45)
Continuity mistake: When the Blues Brothers are paying the assessment in the Cook County Assessor's Office, the area behind the assessor has a desk and is not very wide. In the shot where the camera has panned out, it shows a much larger area behind the assessor. Additionally, how did all of the emergency services personnel get in the room without anyone in the shot seeing or hearing them. When it cuts to this scene, the Blues Brothers look surprised, but they should have easily seen and heard this. (02:18:44)
Continuity mistake: In the scene where they go to Elwood's apartment, Elwood puts on a 78 RPM Decca Louis Jordan record. The record is entitled "Saturday Night Fish Fry". But the song that plays is "Let The Good Times Roll".
Factual error: Legitimate religious institutions are not subject to property taxes.
Continuity mistake: When the Blues Brothers go off the highway down the steep embankment, the cops are directly behind them, however when we cut to the shot of the first cop car crashing, the Blues Brothers' vehicle is nowhere to be seen on the side road up ahead.
Continuity mistake: In the scene where the Blues Brothers visit the Penguin, the door Elwood opens while running away closes between shots and he is seen opening it twice.
