Audio problem: When Chase pulls out the key to MSA, you hear the sound of many keys clanging together. However, if you look closely, there is only one key on the ring.
Continuity mistake: Tris tries to seduce Nick at the river by dancing in front of the headlights of his car. He decides to abandon her, and backs the car away. When he cranks the steering wheel clockwise and points the car up river to leave, the camera cuts to a shot of Tris standing by the river, but the headlights are still on her.
Factual error: In a scene that is twenty-eight minutes into the movie, one of the characters is seen running up to check out a new Cadillac that had been given to him by the owner of Chess Records. A 'super' appears at the bottom of the screen which reads "1952" in order to set the chronological time. Only problem is, the Cadillac is a 1956 model. Any old car buff, particularly one like myself who writes a weekly column for the St. Louis Post-Dispatch, would know in a heartbeat that this car was four years ahead of the year indicated on the screen.

Factual error: In the scene when ADD is first leaving to go on tour, they drive past the Rock and Roll Hall of Fame and the bus driver announces, "On your left..." The shot of the museum as they drive by is the front. The road going by this way dead ends; there would be no way for them to get on the highway or a surface road. (Look on Google Maps. They are on East 9th Street going northwest.)
Factual error: The Major and the band are (correctly) summonsed to appear before a magistrates' court for driving without insurance, but then appear before a judge in full robes. Judges do not sit in magistrates' courts.
Revealing mistake: When Louis is trying to get Lester to apologize to Cleo after hitting her, lots of extras on the sidewalk and across the street can be seen watching the whole scene being shot.
Continuity mistake: When she goes to sing "Nobody's Perfect," she has on a white tank top, a blue jean vest, and a watch. As she starts to sing, she only has the white tank top on, and no vest or watch. Then again throughout the song, she has the vest and watch back on.
Continuity mistake: In the scene where the drama teacher is in the copy shop trying to decide what color paper to buy, his hand keeps moving between shots. Every time the shot is from the copy shop side of the counter, the drama teacher's right hand is in front of the blue paper. But every time the shot is from the drama teacher's side of the counter, his right hand is in front of the orange paper.
Revealing mistake: At the beginning of the funeral for the girl who died in the motorcycle accident, the supposed corpse can be seen breathing. (01:14:35)
