Revealing: The kid in the wheelchair is playing a gamegear with no game in it.

Revealing: In one scene, after a massive car chase, the end result is a city bus twirling round and round. Look under the bus and you can clearly see the mechanism supporting it.

Visible crew/equipment: Jackie Chan picks up a little girl out of the path of the on-coming hovercraft and throws her to her mother. He clearly throws a doll.

Revealing: When the hover craft throws the bad guy into the tree on the golf course, you can plainly see the wire helping him to swing into it.

Other: During a chase scene with the hovercraft near the waterfront in NYC you can see mountains in the distance. Not in NYC.

Revealing: When Keung meets the gang the first time he throws one of them into a pile of Pepsi cans in the grocery store. You can see that the cans are empty. So why were they piled up?

Continuity: When Jackie is fighting the gang at their place the black shirt he is wearing gets dirty one shot and is clean the next shot.

Continuity: When Jackie is on the side of the hovercraft and he fall off, he rolls under a transport which, in that shot is sliding. In the next it is stopped, the next it is moving and then it is stopped again.

Revealing: When Keung hits the mobster in the face with the football helmet, you can see his bruise appear a split second prior to contact. You can see it better in slow-mo.

Factual error: Throughout the entire film there are shots of coniferous forests, lakes, and mountains; this is all obviously British Columbia, Canada (where it was filmed), and not in the Bronx, where the film was set.

Continuity: Why is Elaine so suddenly friendly towards Jackie at the end of the film, when she boards the hovercraft? Why is she even there? And most importantly, why is her hair so short?

Continuity: When Jackie is fighting the gang at their place, he hits someone over the head with a glass bottle. The noise it makes is metallic.

Revealing: Although set in the Bronx, trolleybuses of BC Transit, Vancouver are seen passing in the background.

Factual error: Jackie goes to the golf course to get revenge on White Tiger. It isn't possible to have fixed the hovercraft that quick, with duct tape, while it was deflated

Continuity: Jackie is in the Lamborghini with the large blade, at the end of the movie. He spins under a transport and you can see that the blade is gone.

Revealing: When Jackie is water skiing behind the hovercraft you can see white plates strapped on the bottom of his shoes which are allowing him to water ski.

Audio problem: In the club in which Nancy is dancing (and Keung goes to talk to her), there is dance music playing. This is not a score to the film/scene, but rather an actual song being played in the club. Then why is there also a rock band playing guitars/bass/drums, and why can't we hear it? It's also quite obvious that the band isn't playing in harmony with that dance song in any form, either.

Factual error: When the hovercraft is stopped after Jackie cuts the side open, it isn't slanted to one side(from the outside view), it is straight.
