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 Time Worm comes out of the stick handle and is coiling around it to the left. The very next shot it is suddenly coiling to the right. (01:12:25)

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.

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.

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.
