Continuity: When Jake and Elwood are running form the police for the first time, they do a 360 degree spin in the middle of an intersection. The car is spinning clockwise but when the camera focuses on Jake the scenery in the back is spinning as if they were going counter-clockwise.

Audio problem: When the band is playing at Ray's music store, Murph is playing a tambourine totally out of synch with the music.

Factual error: The palace that The Blues Brothers do their big show in is supposed to be in Indiana. The flags that fly outside the hall are Ohio's state flag.

Continuity: When the Country & Western band chases Jake & Elwood, they start out of the bar parking lot in a full sized RV, but when they wreck shortly thereafter, it's a pickup truck with a camper.

Continuity: In the scene where 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.

Continuity: 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.

Revealing: If you look at Elwood when he sings Rawhide you can see that Dan Aykroyd was replaced by someone thinner and taller.
