Audio problem: When the head of the Nazi forced labor camp is on his balcony shooting workers that aren't working, he fires two shots, kills two workers then reloads for a third shot but doesn't shoot. When he goes back inside, he ejects the live round he chambered onto his girlfriend, but when the round hits the floor, it clanks like an empty shell.
Audio problem: During the award ceremony when the (supposedly live) crooner sings Spanish eyes his lip syncing and the audio editing is awful.
Audio problem: In the scene in the beginning when the dance is going on, it shows John playing the trumpet. When he starts on his solo, there is s shot where it zooms in on the bell of the trumpet. During this shot you hear a single note being played and not changing. But if you look, you can see John moving his fingers on the valves.
Audio problem: After Frida comes back to New York City from visiting her mother, she greets Diego. In the far shot her lips don't move at all.

Audio problem: When Loretta is recording her first record, you hear the snare drum being hit on the drum head but the drummer is actually doing a rim shot.
Audio problem: When Vercingétorix tells Caesar that Alexander the Great was dead by the time he was Caesar's age, his mouth movements don't match the words. In this shot he is, I think, speaking French with the English dubbed over - he looks like he is saying 'mort'. (00:24:50)
Audio problem: The original audio track for the saloon scene towards the end was accidentally lost during filming. Because the film was largely ad-libbed, not all of the lines could be recalled when the scene was dubbed in post production. As a result, lip movement is matched rather poorly to the audio.
Audio problem: When the Scots are applying a battering ram to the city gates, you can plainly hear someone shout "Stop, drop and roll", after the English set fire to the battering ram. (01:29:35)
Audio problem: When Millie comes to see the grieving Beatrix, she presses her face to the door and pleads with her to come out. If you watch the mouth movements of her shadow, they do not match what you hear her say.
Audio problem: The day after Operation Mardonius, when the first set of bombs explodes you first see the explosion and then hear it after a second, then as the last bombs explode you both see and hear the sound at the same time.
Audio problem: Upon Elizabeth's first meeting with the Duke of Anjou, he whispers, in French, what he would like to do to her in bed. Then he says, in English, "Would you like that?" His lips don't move when he says it.
Audio problem: In a shot during the scene with "Big Girls Don't Cry," when Frankie Valli sings, "Baby, I was cruel," the soundtrack is going, they're dancing, but Frankie is not singing - or at least, his lips aren't moving. (01:00:20)
Audio problem: When Brian is rehearsing with his band, the flautists are heard playing whilst their instruments remain on their laps. (Moments later, the same phrase is repeated, but this time the flautists are playing it).
Audio problem: During "This is me", when they enter the room and get to the "oooh oh oh" part if you watch the albino the sync is out as their mouths open after the music has ended on that part.
Audio problem: During the last scene with Ken, he is talking to Phil, as he jumps into the J-Car. He starts the car and the sound of the car is not that of a carbureted 7.0L (427) V8 (which is what it should be) but the sound from a 2005-2006 Ford GT. This is the car Ford sold for 2 years as a tribute to the GT40. The start up sound with the supercharged V8 (which is in the GT) is unmistakable. Especially to car people. When he's accelerating the engine/exhaust sound changes to the 7.0L (727) V8. (02:18:51)
Audio problem: During the birthday sequence, the singer's voice is not in sync with his lips when he is seen on the background. He sings when there's only music sounding and no voice.

Audio problem: After the boat race when one of the Winklevoss twins (hard to distinguish which one) says "Let's gut the fricking nerd", you can see him mouth "fucking nerd." "Fricking" also sounds extremely dubbed in.
Audio problem: During the girls' follow-up discussion after Tracy has sex with Ravi, Evie laughs and says, "What? We didn't go over that one." However, her lips aren't moving when she speaks the second sentence; the second part was obviously dubbed in later.
