New today Continuity mistake: During the shower scene where Beca and Chloe song Titanium, Beca begins the shower wearing gauged spike earrings but when Chloe startles her they are regular silver earrings and they remain that way for the rest of the scene.
New this month 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.
Continuity mistake: In the scene where Beca is going to do night shift at the radio station,when she is unlocking the door to the radio station she has a handbag on her shoulder but when she enters the booth in the radio station she has a backpack on her back instead of a handbag.
Continuity mistake: During the finals, Cynthia Rose's blazer is done up, but during the next shot, it's undone, then the next shot shows it's done up.
Continuity mistake: During the Bella's performance of I Saw The Sign in which Beca starts singing Bulletproof, when Chloe sings the line "like me care for you" the camera focuses on the audience and there an older woman with glasses sitting next to a guy in a blue shirt, but in the next shot the woman has moved seats, and is now sitting next to a guy in a yellow shirt in the row behind the judges' table.
Visible crew/equipment: During the Finals of the International Championships at the end of the movie. Beca is singing "Don't you forget about me" the camera cuts to Jesse sitting in the crowd with Donald sitting next to him, in a few of these shots, You can see crew in the reflection off Donald's glasses and an empty stage.
Continuity mistake: In the scene where Beca and Jesse are in the radio station for the first time, Beca's hair changes from pulled behind her ear to loose between shots.
Character mistake: At the activities fair, after Benji and Jesse walk away from the Treblemakers, Bumper says "Let's match pitch." Then sings a note. The rest of the Treblemakers harmonize, rather than match the note that Bumper sings.
Continuity mistake: In the picnic scene, there is one extra in the background with a blue shirt and jean shorts that walks by three times.
Continuity mistake: At the second competition when Beca runs out, you can see the family walking down the hall with the mom, dad and son in that order from left to right. When Benji runs out after her, the kid is then in the middle.
Continuity mistake: In the party scene when they show Bumper and Donald, a girl with a green shirt and a leather jacket walks down the aisle. When Fat Amy approaches Bumper, the same girl walks down the aisle as if she is just arriving.
Continuity mistake: The water bottle to Fat Amy's right on the floor is present in 1 shot and next shot it is moved behind her much farther away.
Continuity mistake: When Beca walks into the radio station at the beginning it says 85.7 on the window but when she walks into the studio the guy inside says 95.7 WBUJ over the tannoy.
Continuity mistake: In the scene where Beca's dad wakes her up for her class her desktop is "awake" (showing her home screen). A few shots later Beca's dad walk towards it and the desktop is on its screensaver then gets bumped to awake. If the screensaver was set to activate after a period of inactivity, it would already have kicked in while Becca slept, not in the short time it's offscreen.
Continuity mistake: When Benji and Jesse are approaching the Treblemakers at the activities fair, and the Treblemakers begin singing "Whip It," The Treblemaker in a blue shirt goes from the steps on the left to the wall on the right between shots, and is back on the steps when we see Aubrey and Chloe watching them.
