Audio problem: When Dre is leaving Meiying's violin practice in the auditorium there is a long shot of her playing her violin showing her left side as Dre walks to the exit. The notes she is playing are vibrato - varying the pitch of the notes by rapidly pivoting the finger on the strings - but her hand is perfectly still. Even though you can only see part of her hand it is obviously that her playing style doesn't match the notes being played.
Audio problem: In the first shot of the small church in Nottingham, you can hear the bells ring. However, the bell on top of the church is not moving as it ought to be.
Audio problem: After Driver leaves the bar where he killed the bouncer, the tach on the dash is showing 4500 revs, while the car's engine noise is nowhere near that.
Audio problem: During the second camp fire scene at night (after the trio have looked in the cave/railway) Mattie finishes talking but in a wide angle shot the character can still be seen moving her mouth but now without any sound.
Audio problem: When Mr. Big and Carrie are talking in the bathroom, from a shot from behind while he talks his jaw moves up and down, but for several seconds he is quiet but his jaw keeps moving. Surely the audio belongs to the front shots.
Audio problem: When the news helicopter descends on the house as the news of the ICC trial breaks on the TV, the helicopter rotor makes no sound or almost no sound until the shot changes to see it, despite it being very loud once it is visible. The sound of its blades also fades very quickly as it leaves, despite any pilot presumably being very careful so close to a building.
Audio problem: When Bretton smashes the painting, he yells in rage twice. The second yell was dubbed in, because his mouth is closed.
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.
