Crew or equipment visible: A cameraman is visible in the overhead shot during the "Braveheart" sequence.
Continuity: In the final game, after the fumble, the ball is picked up. But in the next shot we see the ball in the lower left corner of the screen bobbling on the ground.
Factual errors: The correct name of the disorder is "Tourette's Syndrome", not "Tourette Syndrome", as it is written on the informational sheet the counselor shows Dizzy and his father.
Continuity: At Danielle's restaurant, the lights that form the shape of a cowboy in the background change from facing the left to facing the right between shots.
Revealing mistakes: When Dizzy goes to the mall to see his girlfriend in the bikini, the extras in the background are standing still for a second before continuing to walk.
Factual errors: At the first football game that Gil goes to, the announcers say that that was the first win since the last Bush was president. Then, when Gil goes into the office and the coach and the principal are thanking him for all he did, the coach then states that it was their first win in five years. The movie was made in 2002 when George W. Bush was president, five years before that Bill Clinton would be president, not George Bush.
Continuity: When Kirk lets go of the motorcycle and it crashes into the garage door the front wheel is on the left, but when shown from the reverse angle the front wheel is still on the left when it should be on the right.
