Audio problem: At the end of the film when Joseph reveals himself to his brothers, he says "I am your brother, Joseph." However, if you look at his lip movements, you'll see that he does not say "Joseph."
Audio problem: When the SEALs in the Chinooks take fire, a helicopter crew member fires their weapons. The weapon is a M240 7.62mm Machine Gun, but the audio of it firing is that of an M134 Minigun.
Audio problem: When Lindbergh calls and waves from the Spirit at the motorcyclist tooling down a dirt road, the motorcycle's tires make a screeching tires-on-asphalt sound as it turns.
Audio problem: In the very first scene of the movie when Bobby is recreating his performance at the Coconut Grove, the actions of the band are out of sync with the music we hear. (Bobby is in sync, but the band is not.) Watch the hands of the drummer and the band leader: The entire scene is out of sync, but when the drummer moves to the ride cymbal you can easily see he is ahead of the music, and when the band leader gives the band cues for accents, his hand movements are behind the music and therefore happen too late.
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)
