Continuity: 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.

Factual error: In a scene where 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.

Audio problem: Near the end, when the officers are getting out of the van, they are shouting "hat, hat," but their lips aren't moving.

Audio problem: In the soul restaurant, when the Aretha Franklin song "Think" is about to end, watch the mouth of the fat lady behind her and you will see that her lips don't match her song.

Other: When Elwood breaks the window of the ladies room (using his hat and fist) and they both climb in, it's not until he says "'Scuse us" that anyone starts screaming, even though some women are right near the window.

Continuity: When the Blues Brothers go to persuade Matt and "Blue" Lou to rejoin the band, and they have just ordered their signature meals from Aretha Franklin, she goes to Matt in the kitchen to moan. Matt is cooking two burgers of some kind, but in a shot of Aretha 30 seconds or so later (when Matt says not to talk that way around his old lady), the burgers have moved and multiplied.

Continuity: When the Blues Brothers park outside Mrs. Tarantino's house, the car's front wheels are almost level with the path to her front door. When they start the car to drive off a bit later, it is parked further back with its front bumper level with the path.

Revealing: In the mall where the police car is spinning around on its roof (when the cop says, "They broke my watch"), you can see there's a separate circle of floor just larger than the car's roof, upon which it is rotating.

Continuity: Where Curtis is getting Elwood and Jake a drink of Jack Daniels, when he gets the bottle it's nearly full, but ten seconds later, after he has got some drinking glasses and starts to pour, it's almost empty.

Continuity: When we see the Nazi's 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.]

Continuity: During the church scene at the beginning of the movie, when Jake is doing cartwheels down the aisle, you can clearly see suspenders attached to the back of his pants. In the next scene, they are gone.

Revealing: When Elwood drives the Blues Mobile backwards from the half-finished bridge, just before it flips you see something on the underside of the car. It's either a coiled spring or a tube with an explosive charge used to flip the car over.

Revealing: In the last scene where we see multiple police cars pile up under the road system, at one point you can see the boards that allow some of the cars to drive on top of the lower cars.

Continuity: At Bob's Country Bunker, Jake takes one of the beers and drinks it. When he grabs another beer, there are the same number of beers there were before (without subtracting the beer he took before).

Continuity: 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.

Continuity: After we've heard why it's so great to be an Illinois Nazi, there's a wide shot of Jake and Elwood's car in a queue, and a policeman walks past the driver's door. In the next shot, the cop hasn't yet walked past the door, and instead of doing so, he stops when the Blues Brothers ask what's going on.

Continuity: Just before the Mystery Girl blows up the building in which Elwood resides, a police car with lights on its roof pulls up outside. When the building actually explodes just over a minute later, you see that the police car parked outside no longer has any lights.

Other: After the state troopers collide with Bob's pickup truck, both vehicles crash into a fire hydrant improbably located alongside a deserted country highway.

Revealing: After Jake topples down the stairs in the desk, the broken remnants of the desk are actually planks of balsa wood cut in the general shape of a desk. The amount of the debris changes from shot to shot.

Revealing: During the last chase scene, pursued by the Nazi's, 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.
