Continuity mistake: When Paige approaches the two girls poolside to "explain the receipt", in the first close-up Jeri-Lynn is touching her own hair while Madison is relaxed. Then the angle changes, and Madison is the one touching her hair, while Jeri isn't. (00:49:55)
Continuity mistake: When Vince Vaughn asks Paige, "Did someone break up with you?" as a comment on her fake tan and dye-job, the girl in front of Paige turns towards him twice, then looks straight again, all between shots. (00:56:30)
Continuity mistake: When Paige embarrasses herself at the boot camp track, she lies with her baseball cap next to her blonde head in the shots from the side, but no cap is in sight in close-ups. (00:58:45)
Continuity mistake: Paige had a pointless argument with the girls on the bus. She is sitting all by herself in front of the gas station. You can see the building is fully sunlit. When the coach approaches her, there's a large shadow over the "Town and Country" sign. It happens again during the scene; the building lighting changes depending on the camera angle. (01:00:20)
Continuity mistake: When Rick and Julia are introducing Paige during their Christmassacre show, the ring (and Nick Frost's bulky figure) is lit differently in the various camera angles. (01:05:40)
Continuity mistake: When Zak pins Paige after a tombstone piledriver, Florence Pugh has a few locks of hair over her right shoulder after several shots when she didn't have any. (01:07:55)
Continuity mistake: Zak is drinking alone in a pub, looking to pick a fight. In the first shot, he has about half a glass of beer left. He drinks in the next shot, but by doing so, he empties a glass that already has barely any beer left. In a third shot, some beer magically appears again for him to drink. (01:11:30)
Continuity mistake: Coach Hutch tries to make one of the applicants quit with his silly horn thing, but Paige steps in. Jeri-Lynn breathes raggedly as she runs one hand through her hair. Which hand though? Her right, in the first shot. Her left, in the second. (01:18:50)
Continuity mistake: A small crowd of people in Norwich are chilling at Ricky and Julia's to watch Paige's first match (even if it's 5 AM, which the movie does not acknowledge at all). When the usually polite mother-in-law screams profanity to cheer Paige, the kid with an afro suddenly is shown resting his chin on his hand, which wasn't true in the previous shot. (01:38:10)
Continuity mistake: When Paige gives the emotional speech (that the actual Paige never gave) after winning the championship, she thanks her family. Cut to said family. Notice the cardboard diva title in Lena Headey's arms. It's upside down, but they fix it right away when it cuts to Nick Frost. (01:40:30)
Continuity mistake: When Julia jokes about her husband crying at the end of Paige's match, he covers his face with either hand, depending on the shot. (01:41:55)
