Another instrument anachronism: In the video for 'Pop Goes My Heart', the bassist is shown playing a Steinberger Synapse series bass guitar. While aesthetically somewhat similar to Steinberger models in the 1980s, the Synapse line wasn't released until the 2000s. (Also of note: he's playing a right-handed bass left-handed, but this is somewhat common considering that many models of guitar are and have been unavailable left-handed.)
There is a scene where Alex and Sophie are walking to the coffee shop. The camera is traveling behind Sophie and Alex but you can clearly see that the audio is not synchronized with the movement of Alex' lips.
During the scene where Sophie and Alex are in the café and he sings "I've got sunshine on a cloudy day..." When it cuts to the camera viewing Sophie, you can see that his lips are not synced with his vocals.
When Alex and Sophie are recording the second take of the song they wrote, Alex starts the computer playing and recording, but when it cuts to a shot from behind them towards the computer, the track is not even playing, let alone recording.
During the scene when Sophie and Alex are having a bite to eat in a café, Sophie's glass of coffee varies throughout the scene. First it's almost full, then the amount of coffee goes down, and then it goes back up. It varies from shot to shot.
Near the beginning of the movie, while visiting Alex Fletcher's apartment, Chris Riley sets a can of Diet Coke on the table clearly displaying the name. Later the can is turned and the label can no longer be read.
When Alex and Sophie are at breakfast, Sophie's cup changes positions several times between shots. Many times, she will lift the cup to take a drink, then in the next shot the cup is back on the table.
During the coffee house scene where Sophie tells Alex about the book, her hands change positions between shots, from both hands on the table, to her lap and back, depending on whether the shot is facing Sophie or Alex.
In the scene where Sophie and Alex are celebrating their success after delivering their demo to Cora on the helicopter pad, Sophie is laughing and jumping up and down when the camera is focused on her, but she is completely still when the camera is focused on Alex. This happens throughout their conversation as the camera's focus changes.
In the scene where Cora is speaking with Alex in the recording studio control room, she is wearing a shirt that says RAMONES (her hair is covering the S). When Cora and Alex are singing in the recording studio, her shirt says JOHNNY and has a different logo on it.
Right when Sophie rearranges the furniture on Alex's apartment, when he says "much better" Sophie smiles at him in a very pleased way and keeps smiling but as the scene goes on the shot changes showing her so concentrated writing, which she was not doing nothing of that at all.
Alex and Sophie are walking down the street where Sophie sees Sloan Cates' book. Walking on the sidewalk, Sophie looks to her right then hides as if she had seen Sloan Cates on her right, but when she comes out of hiding, the book is on the sidewalk she is on, just a few steps in front of her.
When Sophie first visits to water the plants, she cuts herself. She sets the watering stuff on the piano and Alex picks them up. After they show Sophie closing the door, Alex switches which hands he is holding the different supplies in.
During Sophie's first visit to Alex' apartment, while she is using the spray bottle on the cactus, she is holding the spray bottle in her right hand with her first two fingers on the "trigger". In the next shot, she has the side of the first pad of her index finger in her mouth. Holding the bottle in this way, she could not have hit the cactus with the inside of her finger. When she returns for the second visit, a bandage is on the second pad of her index finger.

When Alex and Sophie are in the piano store, and he is trying to convince her to become his lyricist, as he is playing a piano, the camera reveals the inside of the piano, the piano's hammers are not moving even though music can be heard coming from the instrument.
When Alex and Cora are singing 'Way Back Into Love' at the concert, there is a shot of Chris and his daughter in the audience, and they turn to look at each other and smile. The video of this clip has been 'reversed' (it is playing backwards); you can tell by watching the people clapping behind them, and the daughter's hair as she turns her head.
