Continuity mistake: When swimfan85 is trying to talk to Ben and he tells her he has homework to get done, she is talking with the nick name swimfan85 but when she signs off it says "swimfan has signed off." They forgot to add the 85.
Other mistake: When Madison is giving a cello concert at her house, there is vibrato in the music that she doesn't do while playing. In the music, there are low notes on the C and G strings, but she only fingers on the A string, and sometimes she forgets to move the bow while playing.
Continuity mistake: When the main character is swimming and then bumps into Josh who is dead, in the shot underwater there is a lot of blood, but when it cuts to above the water, there is no blood in the water, and when it cuts back to below the water, there is a lot of blood again.
Continuity mistake: When Madison seduces the guy in the pool, she enters the pool but never puts her head under the water. But in the close up of the two making out, all of her hair is soaked as if she dunked her head.
Continuity mistake: When Ben is talking to swimfan online, in the shot facing him he is typing quickly and smoothly. When it cuts to the computer, he is typing slowly.
Visible crew/equipment: When they pull up in the car at Swimfan's house after the pool bit, you can see crew members in the reflection of the side mirrors.
Continuity mistake: In one of the scenes where the main actor is driving his truck, there is a broken orange light on the roof. When the truck is shown a few scenes later the light is fixed.
Continuity mistake: After Ben nearly hits Madison, he gives her a ride home and she leaves her music notebook in his truck. When Ben is sitting in his room mulling over returning the book to her, the diminished amount of daylight coming into his room suggests that it is early evening approaching sunset. Yet, when he goes to her house to give her the notebook, the sun is shining brightly as if it were still afternoon.
Factual error: There is no way Ben would get his drug test results back the same day. High school athletes are also rarely even tested for drug use, this occurs mostly in Collegiate and Pro sports. Also, when athletes are tested, a witness of the same sex is always present. The urine is then sent to a lab for testing which can take at least a few days.
Continuity mistake: In various scenes, you see inspection stickers on the windshield of the main guy's truck, then they disappear.
Continuity mistake: When Ben and his girlfriend are in the diner where she works, they're talking at the bar (the scene right before the one with Madison and Josh making out in the car), and Ben's girlfriend tells him that she thinks he should leave. In her close-up her head is resting on her arms, which are crossed. Next shot, when Ben is walking toward the exit, she's sitting up straight. Then in her next close-up, her head is once again on her crossed arms.
Character mistake: Right before Madison shoots the 2 police officers they show a close-up of the gun in its holster. The holster is unbuttoned. No police officer would leave his gun holster unbuttoned, especially while sitting next to a felon.
Revealing mistake: When Amy and Ben are sitting on the stairs talking and she asks him if he was freaked out about her saying that they could move in together, if you look in between the bottom stair rails, there is a man in a yellow shirt jumping up and down waving his arms.
Continuity mistake: When Madison pushes Amy into the pool while handcuffed to a chair, the camera shows a close up of her handcuffs behind her back at the bottom of the pool. Amy's handcuffs were applied with the swinging jaws inward, towards her back. In a subsequent shot, Ben is picking the handcuffs to free her and the swinging jaws are facing outward.
Continuity mistake: When Ben and Josh are talking in the locker room for swimming, Ben has all of his clothes on. We see Josh for a second and then go back to Ben who is now in his bathing suit.
Revealing mistake: In the pool scene after Ben saves Amy, Ben turns to Swimfan. If you look closely at Swimfans feet you can see she is wading in the pool.
Continuity mistake: When Ben and Madison are in the pool together for the first time, the camera is behind Madison. You can see that Ben's hair is completely wet and slicked down. When the camera is behind his back, his hair looks more dry and a little is sticking up on top.
Continuity mistake: In the scene at the party, when Ben is introduced to Madison, and then she meets him outside the bathroom, she pulls her cardigan down off one shoulder. In the next shot it is off both shoulders and in the shot after that it is only off one shoulder again.
Continuity mistake: When they are at the party, Ben first walks in, takes off his jacket and drops it in a chair, then he proceeds to hug Amy and gets introduced to Madison. In one shot his jacket is off, in the next it's on, then it's off again.
