- Continuity: During Maggie's first fight, the manager takes her mouthpiece and rinses it but never gives it back to her.
- Errors in geography: When Maggie is taking her mother to the new home she just bought her, there are palm trees around the other houses in the neighborhood. This scene is supposed to be in a small town in Missouri, where palm trees do not grow.
- Continuity: The "Everlast" patch on the speed bag moves repeatedly between shots after Frankie begins to train Maggie (the last half of the speed bag scene).
- Crew or equipment visible: When Frankie introduces Maggie to one of the managers at the gym, movie lights can be seen reflected in the sunglasses hanging on his shirt.

- Errors made by characters (possibly deliberate errors by the filmmakers): Eddie Dupris claims that a knockout is caused when the neck turns a certain degree after which the human body takes over and shuts itself down for safety reasons. While generally unknown, it is widely believed that a knockout is actually caused by the rattling of the brain against the skull causing severe trauma resulting in a concussion.

- Errors in geography: When Frankie & Maggie leave Maggie's hometown of Theodosia, MO, they pass a road sign with "160" inside a Missouri outline, the correct sign for Missouri State Highway 160. However, the main highway through real-life Theodosia (in far southern Missouri, just north of the Arkansas border and east of Branson) is U.S. Highway 160.
