All of the film's battles were very competitive in real life. The fight that breaks out during the first battle with Wade's crew was not in the script, but everyone was so mad at each other that they just started fighting. While filming the opening battle, the director would yell "cut", but Omarion Grandberry kept battling with Columbus Short. Omari does a back flip, while at the same time Columbus does a move that looks like he is pulling David up. This was not in the original choreography; it was a true battle.
During the final battle. Omarion Grandberry's character has his hat knocked off when another dancer puts his arm around his neck, but almost directly after that the camera changes and his hat is back on securely.
In the Big Bounce battle, one of the dancers on David and Elgin's crew has his pant leg rolled up. While he is dancing, his pants keep on going up and down.
Although the Big Bounce dance at the end was being covered by TV crews, you can actually see this movie's film cameras and crew trying to blend in and shoot the action from various angles.
