Audio problem: In the beginning, Claudette and the other counsellors are all singing. When they get closer you can see that Claudette is playing the guitar, then she stops, but the guitar playing and singing still continues. (00:02:10)
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)
Audio problem: When Sonny arrives at work, as the Security Guards open the gates for him, we hear them chatting, but their mouths aren't open/are out of sync.
Audio problem: Before the trio crashed into the Daily Planet (just before the battle with Supes), they were heard flying outside the building. For 3 superbeings with the ability to fly unaided, they sure sound heckuva lot like jet-propelled aircrafts. Jet aircrafts are noisy because of their engines, but superpeople?
Audio problem: When the nurse from Keto crashes out of the window - you hear the window smash. Half way through his fall - you hear the window smash again.
Audio problem: When the zombie guys are breaking the windows at the church, you can hear multiple pieces of glass hit the ground even though almost no pieces fall.
Audio problem: In the last scene of the film, when Gere is in prison and talking to another using the telephone behind glass, we hear his voice as if via a telephone. Most of the speech is done this way then for the last line he puts the telephone down on the desk, but we can still hear his voice as if he was still using it.
Audio problem: When Al Czervik pays the band leader to play something hot, they stop playing slow music and a disco song starts up. The disco song is obviously the original studio recording and not the clubhouse band. The female vocal accompaniments from the recording can be heard, but there were no female vocalists with the clubhouse band. (00:36:10)
Audio problem: At the illegal fight, as Castor and Oxheart get ready to fight, Oxheart's mom says "Don't kill him. Just rough him up a bit." you hear the lines, but her mouth isn't moving.
Audio problem: When the three ladies (Violet, Judy, Doralee) are at the hospital standing at the phone booth, Violet is digging through her purse for some change to make a call and asks Judy if she has any. Their voices sound echoey, indicating the scene was possibly shot on a sound stage and Doralee's line sounds a tad choppy.
