Audio problem: Much of Johnny's dialog is dubbed in throughout the film, with his lips and dialog not quite matching. (This is due to actor/director Tommy Wiseau's thick accent making the original dialogue sometimes hard to understand).
Audio problem: When Lizzie is performing at the end of the movie at the awards show, at the part where we see her from the back facing the blue light, her voice sounds like it's changing. It seems like it's someone much older singing, or the synthesizer went wrong. It just obviously isn't Lizzie's voice anymore.

Audio problem: When Mashkov's men grab Steve, you can hear him say "Come on, Charlie", but his lips aren't moving at all. (01:39:35)
Audio problem: At the battle on the fields of Pelennor, before Legolas leaps onto the Mûmak, as he kills the Orcs audibly he shouts, "Fifteen! Sixteen!"; however, visually his lips do not. (02:12:05)

Audio problem: During the wild boar hunt, they are interrupted by Aleander who says, "Prince Frederick of Saxony. He refuses to surrender Luther to you, Your Holiness," but nothing matches his lip movements. He utters a couple of syllables, at most, out of sync with the two full sentences heard in the movie. (English DVD version). (01:03:15)

Audio problem: When the couple is flying to their vacation destination, they are in a Turbo-Prop aircraft. The sound affect used was from a piston engined aircraft.
Audio problem: At the classy restaurant, watch the man playing the drums. The brushes that he's supposedly using to play the snare drum are an absurd 5-6 inches higher than the drum, making it obvious that he wasn't really playing, and that the music was dubbed in. (00:53:15)
Audio problem: After Dewey and Miss Mullins go to the bar, Dewey is heard singing and snapping his fingers as he drives. However, you can see through the windshield that both of his hands are on the steering wheel and he is not snapping his fingers.
Audio problem: As soon as Nemo begins playing the record, we hear a woman say "Ready, professor?". However, the actual recording doesn't start until the needle is put into position, which is after she says that.
