When Max is having his breakfast from a bowl at the beginning of the movie, the camera is close and the bowl is high, the camera pans out and the bowl is suddenly low, yet when the camera does a close up again, the bowl is high again. He didn't have time to put it back up or get it to the right height.
During the meet, you can see Max Taylor in the stands, behind the judges yet the girls admit later that he couldn't make it to the meet because he was too upset about the break up between him and Brooke.
When Brooke drives up to see Max with the model, a crew member's head appears in the reflection of her car window.
