Audio problem: In the scene where Christina Milian is auditioning for John Travolta and Uma Thurman, it is painfully obvious that the audio for her song was pre-recorded. Her voice sounds distant, as if it were miles away.

As she walks past Martha Tabram and Annie Chapman, we hear some dialogue between them about not having very much luck that night. If you look at all three women, their mouths are not matching the dialogue. They appear to be saying something completely different.

Audio problem: When Cutter rolls and shoots at Vincent, we can hear the distinct sound of his pistol. However, we see a shot of the pistol's slide in the open/locked position, meaning he's run out of ammo, but we can still hear the pistol being fired a few times after that.

Audio problem: When Halloran and Hunt are discussing orders from the commissioner to exhume Jigsaw, it's clear that several of Halloran's lines have been looped in post. His voice is a bit too loud and a bit more forceful than he appears to be speaking, and at least one word doesn't quite line up with his mouth movements. It can be hard to spot the first time, but if you look for it, it's noticeable. (Confirmed in DVD/Blu-Ray commentary - the actor lost his voice and his lines had to be looped).
