Goofs

During the scene when Rod and Denise first kiss, Rod has his helmet on and it is strapped. Before they kiss, Rod takes off the helmet and the strap isn't strapped anymore.

When Rod is about to jump the pool, he waves at Denise and you can see a ring on his hand that is not present anywhere else during the movie.

After Rod falls down the hill, when he is telling the crew that they are going to raise money to save Frank's life, Dave has a mug which changes from his hands to the table between shots.

When Rod is asking out the cashier, a drink appears between them when they show Rod, and then disappears.

Near the closing of the movie, when Rod is seen growing a mustache of his own, the facial hair itself changes in length throughout the next few scenes.

Rod attempts to raise $50,000 for his stepfather's heart transplant. In 2007, when the film was released, the cost of obtaining a donor heart alone would have cost around $90,000. The total cost of the transplant, including doctor's fees, hospital costs, post-op care, etc. would be over $650,000.

As explained sensei is the honorific term for teachers in Japanese. For Tai Chi the equivalent is "Sifu".

When Denise and Rod were practicing Tai-chi by a lake, Rod refers to Denise as "sensei". Tai-chi is a Chinese martial art. Sensei is the Japanese pronunciation of the honorific term for teachers, not Chinese.

Several times throughout the movie, we can see police cars in the background blocking off the streets used during filming.

During the scene where all four of the Hot Rod team is marching down the street and the large crowd forms behind them, you can clearly see a Canadian RCMP car parked at the building in the immediate background. About 5-10 seconds later when it cuts back to the same shot, it has disappeared mysteriously. According to the story, this film takes place in the US state of Washington.

The film is supposed to take place in Washington state, but a Canadian bus from British Columbia Transit appears in the film.

A Canadian MAXIMUM 30 speed limit sign (Canadian signs read MAXIMUM in place of SPEED LIMIT) appears clearly when Rod does his luge down the hill. The movie is supposed to take place in Washington state.

After the riot Rico is seen carrying a television set, even while running. In the next scene Rico still has the TV, but when they stop to discuss what happened he isn't carrying it anymore.
