Audio problem: In the scene where Jack Bondurant is loading jars into the back of the truck, Floyd Banner is driven into town and screeches to a halt nearby. Although the tyres screech which is characteristic of tyres stopping suddenly/losing traction on Tarmac or cement, the car is on a loose dirt road.
Audio problem: When Heather is reading her dads note in the car to Silent Hill, the letter and the voice over do not match. (the second paragraph starts off by saying: "But you desire" and the last word right before "I love you" is "place" but through out the reading you do not hear those words.
Audio problem: In the opening scene the camera shows a close up of "Bumper singing please don't stop the" (repeatedly) then pans to the Bellas off stage. His singing doesn't match the audio. In fact several times during that performance there is audio of him singing but his mouth is not moving. (00:01:30)
Audio problem: During the escape from Monte Carlo they all drive a van off a roof to land on the roof of the Hotel Ambassador. Captain DuBois drives her bike of the same roof to catch them. While she is in airborne she jumps off her bike onto the roof of the Hotel Ambassador and the bike falls to the ground. Yet we don't even hear the bike landing on the ground at no point despite the fall only taking a few moments. (00:17:35)
