Continuity mistake: When the real 'manager' comes outside to yell at "Mr. O'Donnell', you see the manager walk back into the club. If you look in the background of the next shot, you can see the manager walking through the door again.
Continuity mistake: Violet drives through the toll booth on her way to sing her song. Then she says that she couldn't do it and made a big U turn. The toll booth wasn't that far behind her but it seemed like she drove a mile and a half before she reached it.
Continuity mistake: When the guy at the bar orders 8 shots and Cammy (the blonde) tosses up 8 shot glasses in a fancy manner, as you can see she throws them up into 2 rows of 4. But then in the next shot they're all just in one long row of eight. It would be impossible for her to arrange them that quickly - there is only about a second between the two shots.
Continuity mistake: When Violet goes to the club for the first time, her boss tears her shirt with her hands in the arms and the belly so that she becomes more sexy. How comes it is so straight later on, as if cut with scissors?
Continuity mistake: Near the beginning at the Violet's going-away party, she and Gloria are up on the stage singing, from one cut to the other Violet and Gloria change places.
Continuity mistake: At the end, when Jersey is trying to sing her own song on stage, before Kevin turns off the lights her hair isn't curled but after the lights come back on her hair is curled.
Continuity mistake: Near the beginning when Violet goes to the open mike night she is wearing jeans, but when she arrives home and finds her apartment broken into she is wearing a skirt and a different shirt. (The skirt and white shirt with the denim jacket that she wore for the first 2 or 3 days).
Revealing mistake: In the scene where Violet sings for Kevin for the first time, he starts to switch the lights off. Notice when he has turned off the lamps, the room is still very bright, but when he blows the candle out, the room is suddenly totally dark. That single candle could not possibly have lit-up the room and the characters the way it did, after the electrical light was switched off.
Continuity mistake: In the last scene when Violet says to Kevin "So what do you do when you realise all your dreams have come true?", Violet moves in to kiss Kevin and she gets really close and then the camera cuts away to a different view and it shows Violet taking a step towards Kevin from 2 - 3 feet away.
Continuity mistake: When the 4 Coyote's are dancing on the bar and pouring water on themselves, in one scene you see Tyra's shirt is totally, completely wet, but in the next, it is dry on the side.
Continuity mistake: When Violet and her boyfriend are getting intimate around all those celebrity cardboard stand-ups her bra strap is down by her elbow. Then the camera cuts in closer and the strap is back up on her shoulder.
Continuity mistake: In the first scene where Lil examines Jersey's arms, the length of her hair is about 6" shorter than throughout the rest of the film. This is because that was one of the first scenes of the whole film they shot.
Continuity mistake: In the scene at the bar when Rachel is trying to get all the females to give her their bras, at first she is on the bar. In the next shot she is behind the bar taking money. The next shot she is on the bar again. She goes from being on the bar to being behind the bar 4 or 5 times in that scene.
Continuity mistake: In the scene where Violet and Kevin are in the CD shop and Kevin is asking Violet to play at his friends club, Violet is wearing a tan and blue necklace and then when the camera takes a shot of Kevin and then goes back to Violet, her necklace has been flipped over and then again when Violet embraces Kevin, her necklace has been flipped around again.
Continuity mistake: During the scene between Piper Perabo and Melanie Lynskey, outside Violet's apartment in Chinatown, Melanie's character, Gloria, is wearing sunglasses on her head. Looking closely, you can notice the overhead lighting reflecting in her sunglasses. Apparently, the sunglasses were not dirtied enough for the light to disappear.
Continuity mistake: In one of the final scenes when Violet is performing at the 'Ballary Ballroom', just after Kevin has turned off the lights and Violet thinks 'Hey, They've all disappeared' and starts to sing, the first few words of the song are sung, but Violet's mouth doesn't move at all, until she suddenly decides to sing a few seconds later... from the beginning.
Continuity mistake: When Zoe, Tyra Banks, is 'crowd surfing', she is heading away from the bar. The next scene is where Violet hands Lil two beers, but in the scene directly after that, you can see all of the girls behind the bar, even Zoe (if you look way back to the right, next to Rachel). There is no way Zoe could have gotten back there that fast.
Continuity mistake: In the scene just before Violet gets her tape back from Kevin they show Kevin dancing. His boss is moving with the music with a cup of coffee in his hand - they cut to a different angle and he is now eating something.
Audio problem: When Violet is trying to get into the apartment because the phone is ringing, she runs in, picks up the phone and says "hello Kevin", but her mouth never moves.
