Audio problem: When Penny and Johnny are teaching Baby their dance routine, Penny puts on a record. Look closely and you can see that Penny moves the arm to place it on the record, then she takes it away, even though the music is still playing. Even if it's a directorial device for us to hear different music than they do, it's still a mistake because she's not actually playing the record, meaning there isn't any music for them to dance to. (00:36:35)
Audio problem: Just after Dynamo kills Weiss, the next shot shows Dynamo approaching the camera. You can see Dynamos lips moving, and he's speaking, but you can't hear anything.
Audio problem: In the scene where Freddy cuts off a doll's head to replace Wondermut's old toy Bob, there is a close-up of the doll head being shaken with Freddy's head visible in the background. You hear Freddy saying, "Look Wondermut. I found Bob," but you can see that Freddie's lips aren't moving.
Audio problem: Regardless of what he has on his feet, every time Gekko walks there is the sound of shoes on the floor, even when it's clear that he has socks/sneakers on.
Audio problem: As Pruitt is beating up the adulterer in the street, despite the sound effects, it's obvious that his punches are missing. (00:27:35)
Audio problem: The dialogue that Michael Douglas hears Glenn Close saying when he walks into his apartment to find Glenn Close talking to his wife is the exact same thing that she says just before she leaves when Ann Archer gives her their phone number.
Audio problem: When E. Johnson and Sam are hiding behind a pile of tyres, spying on Lester, after Lester's group has pushed the caravan off the cliff, Johnson gets up and says "We're gonna take a little detour," but her mouth is shut. (00:32:00)
Audio problem: In the sniper scene, Bond is asked if he wishes to use the soft-nosed bullets to kill the potential assassin to which he replies, 'No the steel-tipped'. There isn't any lip movement, however, after the word 'no'.
Audio problem: After the "Off to See the World" part, it shows Klaus and Claudia in the pool. The waiter tells Claudia that there's a long distance phone call for her from Europe. "Wonderful!" Claudia says, and she slides off her raft and while she makes her way out of the pool, accidentally drops water on Sophie. The dog freaks out, trying to paw the water off her and Klaus snickers at her. After the shot of snickering Klaus, it shows Sophie turning her head towards Claudia and you could hear her bark. However, she does not move her mouth as if she's barking and the barking noise sounds quite perky.
Audio problem: Ness grabs a man who's trying to blackmail him and throws him out of the office. When he does, his voice changes abruptly, much cleaner, obviously overdubbed, and the sentence "You tell Capone that I'll see him in hell" is heard but Ness doesn't mouth it.
Audio problem: When Ritchie is playing in the country bar, Bob's drumming is inconsistent with the drum sounds.
Audio problem: The keyboard Kevin gets from the music shop seems to have an interesting trait, in that the high notes are on the left. This must either be bad "audio dubbing" or something to do with the shot perhaps being reversed, although I doubt this. It's most likely a post-production audio error as very very few keyboards or pianos are configured in this way.
Audio problem: The radar operator (making the sounds of a garbled intercom) is laughing through his next line "I'm having trouble with the radar, Sir." (After/when Dark Helmet throws the intercom across the control panel). (00:21:45)
Audio problem: In the mansion, the boys open a secret passage and fall through the floor. They scream after shining a flashlight on a skeleton. Eugene then can be heard whining that he wants to go home, but his mouth is not moving.
Audio problem: It's quite obvious that all of the grunts and sounds of terror that Ash makes while his hand is attacking him in the kitchen are dubbed. (00:28:45)
Audio problem: On the moon, Superman smashes Nuclear Man's head against his knee. The clonk is heard before the hit (even forgetting that sound can't be heard on the moon).
Audio problem: At the wedding, Nadia sees Walter across the pool and in the close-up of her face we hear her let out a loud shriek, but visually she does no such thing. (01:29:55)
Audio problem: When the biker shows up at the end, Holly Hunter asks Cage what he is, to which Cage replies "Do you see it too?" but his mouth is not in sync with what he is saying.
Audio problem: When Lord Crumb says "Once the Fast Food authorities have checked the samples..." his mouth movements are way out of sync with the audio. (00:45:50)
Audio problem: After Dutch has fired the rocket at the Predator standing on the log, the Predator shoots several times. Then you can hear it shoot one more time, but you can't see any blast coming from it. (01:24:35)
