Goofs

Upon being picked up by the taxicab, Beca has four black bags/suitcases, plus her black laptop bag placed into the taxicab's trunk. Upon arrival at Barden, she grabs the laptop bag, while a yellow-shirted volunteer unloads the trunk. The bags do not follow her to her dorm, and once in the room, Beca is unpacking boxes and a brown duffel bag.

Aubrey is talking to The Barden Bellas about rehearsal times when standing in front of a white board displaying the rehearsal schedule. Aubrey says "we will practice every day for at least two hours seven days a week..." however the board behind her clearly says under Sunday: "No rehearsals - enjoy it!"

When the guys come in to announce there's no one left to audition, Aubrey and Chloe have no one sitting behind them. The shot changes and there are 2 people sitting behind them. When Beca enters, those people disappear again.

When Chloe, Aubrey and Fat Amy are fighting, Lilly attempts to join the group and is wearing a green bow on top of her head. Fat Amy pushes her out of the way and Lilly's bow falls off. When she lands in the pool of vomit in the next shot, the bow is on her head again.

When Aubrey is telling Beca she needs to take out her ear monstrosities, Beca's hair goes from being loose by her face to tucked behind her ear several times.

Twice we see the sign on the door of the radio station showing 85.7 FM while we hear it advertised as 95.7 FM. (Also, frequencies below 87.5 FM are not used in the United States.) Also, radio stations based at educational institutions in the United States are based between 87.5 and 91.5 FM.

When Beca is shown lying back in the park with her headphones on, you can clearly see the red headphone channel designation "bean" with the letter "R" being worn over her left ear. A music nut like Beca would never wear headphones with the channels reversed.

(On this model headphone the cord extends from the left side and the filmmakers likely didn't want the cord in the shot.)

The Bellas consistently sing one line in "The Sign" as "I've left you all alone", but the real lyrics are just "I've left you" followed by some "oh"s.

Beca says that in German "Vader" means father and thus this gives the plot away of Vader being Lukes father. However in German it is written as 'vater' with a hard 'va' sound. She means Dutch where both the written (vader) and pronunciation (vadur) matches his name Vader.

The DVD cover of the Breakfast Club (High School Reunion Collection) does not match the cover of the actual release. There's too much blank space between the movie's title and the main cast photo towards the bottom.

When Kimmy-Jin is playing Wii with her friends, they are not using Wii-motes. Instead some are using their cell phones and there is one using an xbox controller.

When Jesse is eating dinner with his family, they are eating next to a kitchen island with a distinctive faucet. Later Beca visits her own father in what is clearly the same kitchen but shot from a different angle; the tell-tale sign is the same island counter-top and the distinctive faucet.

When Jesse is about to start the end of The Breakfast Club (1985), he turns one of the lamps next to Beca's bed off. Since there is a light on Beca's desk, the room should still be lit, but the room goes completely dark.

When Jesse is backing up during their set at finals, you can see that his jacket got caught on his arm. He then shakes it off, the scene switches frames to just Jesse and Benji's face where you can see his shoulders did not move at all. Then, another frame switch and his blazer is caught on his arm again.

Just before Beca's attempt to make amends with Jesse, she turns a corner on the way to his room. As the shot begins, there is an extra "walking" down the hallway in the opposite direction; however it is clear that the extra was standing still as the shot began and started walking as Beca turned the corner, which looks highly unnatural.

Beca enters the radio station when she enters the studio you can see that the studio door has "Studio Authorized personnel only" written on it, but on the side that you could read it correctly there's blinds covering the window.

When Lilly is singing in the audition, she is shown having a very quiet voice and you can't even hear her (until the end of the movie). Then in the initiation scene a few minutes later, they have the Bella's say "I, (sing your name)". It is when they are singing that you can hear Lilly belt out her name louder than the other girls.

At the a-ca-initiation party, "I Can Feel It" is selected on the MacBook but "Keep Your Head Up" starts playing and even though Justin hits keys, the play button isn't actually pushed (the play symbol doesn't change to a pause symbol).

When Chloe says, "see ya, later!" to Beca, her mouth doesn't form the words.

During the activities fair, Aubrey and Chloe say that they need to recruit 8 girls. Thus, a team to be able compete in the ICCAs must have at least 10 members. However, when the Regionals are happening the team with the pink dresses standing in front of the Bellas has only 8 members present and the team on stage (the Sockapellas) has only 6 members.

However, the 10 people minimum for the ICCAs is an assumption. That isn't stated as fact in the film. It may just be that they needed 10 people for their group.

At the activities fair after Benji and Jesse greet Bumper, Bumper tells the Treblemakers to match pitch, however they do not match pitch, they harmonize.

Beca says that Vader means father in German, but in fact the language is Netherlands Dutch. The German word for father is Vater.

When Beca is lying back in the park with her headphones on, she has the one labelled "R" over her left ear. A music nut like Beca would never wear headphones with the channels reversed. (On this model headphone the cord extends from the left side and the filmmakers likely didn't want the cord in the shot.)

The competition is referred to as the International Championship but at the end of the movie, the student running the auditions refers to it as the National Championship.

When the girls are notified that a competing team was disqualified and that they are now going to the finals, one of the Cynthia Rose is shown playing poker. They were playing from left to right and poker is played from right to left.

However, whilst playing from right to left is standard there is nothing stopping a group from playing left to right if they want to.
