Factual error: The bad guys attach over a pound of Semtex to the hull of the First Lady's yacht. When it explodes, the blast shatters the windows in a house a mile away, yet apparently doesn't impact the hull. Even as the vessel burns for 5 minutes, there is no discernible list.
Continuity mistake: The dragon on Jinx's shirt changes in size throughout the movie.
Continuity mistake: Near the beginning of the film, the soldiers are filling sand bags with mud. Beletsky, whose hands and forearms are covered in wet mud, puts down his sandbag and takes out a photo of his girlfriend. In the next closeup shot of him holding the photo, his hands are suddenly clean and dry. (00:11:00)
Revealing mistake: Terri is replaced by a stuntman in a dark blond wig once she puts on her motorcycle helmet outside the hardware store.
Revealing mistake: When Frank Bauggs is falling from the building, he is a very obvious dummy. His body limps around too much. (00:50:45)
Continuity mistake: Donna holds the newspaper with the news about the murder of her father, then hands it to Taryn. Shot changes and the paper is back in her hands.
Factual error: In the farmhouse bedroom scene, the lead character wakes up and a close up shot of the alarm clock shows it is 5AM. Full sunlight is coming through the window, and an exterior shot shows the sun shining on the house and hay bales. The narrative lead-in just explained that it is early October on a farm near Dallas, Texas. The earliest sunrise occurs near Dallas in October is 6:40AM. (00:04:00)
Continuity mistake: Rick Latimer is at the bar with his buddies. He spots his ex-wife on a date with the divorce attorney and begins rambling. "This kind of sh. Happens", one of his friends says. The friend next to him, rightmost position, is smoking, and his hand is suddenly raised at the cut. (00:02:45)
Revealing mistake: A bunch of seedy individuals are gathered, weapons in hand. Unbeknownst to them, though, deadly ninjas are creeping by, with all the speed of fast-forwarded footage. The problem, besides how obvious the trick is, is that it also features a visible jump cut; you can see the foliage change position literally from one frame to the other during the same shot. (00:01:30)
Continuity mistake: When the pirates swears the oath to kill Dragon Mao, they drip blood on one of the pirate's hand. The blood stains on his hand differ between the shots. (00:02:50)
