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)

Pitch Perfect (2012)
1 audio problem - chronological order
Directed by: Jason Moore
Starring: Anna Kendrick, Rebel Wilson, Brittany Snow, Skylar Astin, Anna Camp, Ben Platt
Character mistake: In the scene where Becca and Jesse have a picnic, she tells Jesse that she knew Darth Vader was Luke's father, because "Vader literally means father in German." This is incorrect. However, it does mean father in Dutch. The German word for father is Vater.





Answer: It wasn't just that she sang a song he likes, she sang arguably the most well-known song from his favorite film in front of a huge crowd of people. It was a public, heartfelt apology rather than the abrupt, private apology she gave earlier.
