The story line dictates that Hayley has been inactive in gymnastics for two years. Based on the results of her leaving Worlds, one would believe that walking out of the IG Classic would yield the same result, disqualification. Without an official result in a competition for two years, she is somehow qualified for the National Championships at the end of the film. However, USAG allows a gymnast to petition their way into a meet if they are for some reason unable to finish the qualifying meet. They use the score from the last FULL USAG Sanctioned meet that the gymnast competed in.
When Joanne and Haley are arguing about who gets to compete in the IG Classic, Haley says that Dalmatians are born with spots, they don't earn them. Dalmatians are actually born with a completely white coat, and their spots develop over time.
When Mina is doing her final vault routine, the color of her bra strap showing is a light, white color. When she has received her score and is being congratulated by her teammates, the color of her bra strap is hot pink.
When Haley first gets into the tub filled with ice, her sports bra is black. Then they cut to a scene where the other girls were watching the sports news and then they switch back to the tub scene where Haley is getting out of the tub and her sports bra is now gray.
When Wei Wei is listening to her iPod in the competition you can clearly see that she is listening to an iPod mini. And when she goes to do her routine they zoom in on the iPod showing the song playing, and it has a picture of the album, and the quality of the graphic is different than that of the iPod mini, showing that the zoomed in on a different iPod.
When Haley Graham got in the truck with those two guys, the front window was very dirty. When they switched the camera position, all of sudden, the front window became crystal clear which in the back window of the car it still has "wash me" on it.
Towards the end of the movie, the judges question the gymnasts regarding who will be competing. As this scene's beginning, Tim's voiceover says, "After what happened to Nastia Liukin and Wei Wei Yong yesterday and Mina Hoyt today, it's safe to say the athletes are sending the judges a message."
The competition was a two day competition, with the first day being the all around and the second day being the event finals. The rebellion only occurred on the second day. Also, Wei Wei hadn't done a routine yet (beam followed this scene) and the order of the event finals was Vault (Mina), Bars (Nastia), this continuity error, then Beam followed by Floor.
Right after Haley tries to apologize to Tricia, as she walks up the stairs and on to the stage and then to her spot in line, the camera is set far back watching the entire stage, as the girls step forward and raise their hand as their name is called, Haley is just getting into line, when Joanne is stepping forward, but when it does a close-up, Haley is already in line, and the person before Joanne is stepping forward, then Joanne proceeds to step forward.
Haley puts on pants when she leaves the gym during the break in the IG Classic. When she is shown re-entering the gym and walking to the beam, her pants have disappeared. After the beam routine, she picks up her pants from a chair off to the side. How did they get there?
When Joanne is talking to Frank and Poot outside the gym, she's wearing a pink and silver swirly leotard. But immediately afterwards, when she goes inside, she's wearing the purple leotard she was wearing before the mall scenes.
Before Wei Wei's scene where she does here beam routine it shows her listening to a first generation iPod Mini. She looks down from the beam onto her screen, which shows a colored album photo to the song Gone Baby Gone, a feature which was not introduced until the iPod Nano on September 7th 2005 (of course the iPod Photo was the first iPod with a color display being released in late 2004).
When the girls are outside arguing about going with Frank and Poot, there's a girl on crutches, with a cast on her lower leg. This is not the cast given to someone with the injury she sustained to her femur.
The movie is set in Texas, yet Haley's mother (played by Australian Gia Carides) is the only character with a Southern accent. However, contrary to popular belief, while a Southern drawl is not uncommon in Texas, a sizable number of Texans speak with a "normal" American accent, including the vast Austin subculture of which this goof-corrector is a member. It's likely an urban-versus-rural difference.
When Burt Vickerman bounces of the trampoline after attempting a full and asks for 911 to be called, he is driven away in a vehicle marked with the words "Harris Co. Fire Department." Some believe this indicates that he was driven away in a fire truck. However, many fire departments have paramedics on staff and own ambulances that go out on emergency calls. Looking at the back of the truck, it is clear that it is the boxy shape of the back of an ambulance, not the shape of a fire engine.
In gymnastics competitions at the national level the individual event finals qualification is the all around competition. Two individual event finals had occurred, vault and bars, before the meet manager inserted "alternate" Tricia Skilken for the beam finals. That suggests that Tricia did not qualify for 3 of the 4 event finals and still, somehow, won the all around competition. Just by the number of gymnasts in each event final this should be mathematically impossible, and since Tricia tried to bust the rebellion on beam, there is no way she would have scratched the first two event finals unless she was injured. However, if she was injured, she would not have competed on beam.
When Haley scratches on vault, Anthem Part Two by Blink 182 starts playing. The word "f*ck" is not silenced the first time the chorus is played, but in the second verse and second chorus, it is silenced. (This is because the movie is rated PG-13, and the MPAA permits only one use of a sexually-derived expletive before the rating must be changed to R.)
During the final meet if you look beyond the first three rows of spectators the stands are clearly filled with dummies to make the arena look full. It becomes obvious when the real people are clapping and cheering and the dummies remain immobile.
When Hayley's on beam at the classic, she's doing a handstand, and a tear falls on the beam. When she rights herself, she has wet trails down her cheeks. The wetness from her tears should have been down her forehead, since she was upside down when she was crying.
On the first day of Championships, after Wei Wei's bars dismount, there's a shot of the crowd, and someone is holding up a 10.0 sign. But you can clearly see the crease where the one was folded back, making it a 0.0 sign, which isn't shown until a later scene.
