Continuity mistake: During the fight between Ryback and Strannix, Strannix cuts Ryback above his left eyebrow with his knife. The cut disappears shortly afterwards, but reappears in a later shot.
Deliberate mistake: When the terrorists attack the ship the shot then goes to an external view of a soldier getting shot. The soldier falls but you can actually see him jump. (01:23:55)
Revealing mistake: When Ryback busts out his fellow mates and hands out weapons to them, the Uzi given to one of his mates does not have a magazine in it. (01:02:20)
Continuity mistake: Krill enters the Captain's room to get him to the party. Krill has a cigar in his mouth and when the camera pans to the captain instantly, Krill's voice says "I'm your date tonight captain" within a split second, with not enough time to take the cigar out of his mouth first.
Audio problem: The two mercenaries Ryback kills in the kitchen have suppressors on their weapons yet you hear every shot as if the suppressors aren't attached.
Continuity mistake: Early in the film, a missile is fired from the ship, and it hits the satellite installation right outside the Navy headquarters (the people in the control room hear the explosion). It gets there very fast. Later in the film, a nuclear missile is sent towards Honolulu. That is supposed to take 24 minutes. Why so long, when the other missile got there much faster?Jacob La Cour
